A Last Look at Open Source BI Open-source BI and I have come to a parting of ways. OS-BI capabilities, reliability, and support have matured. Commercial OS-BI vendors now compete with BI market leaders.

I will, however, take one last look, a snapshot of the state of the market, before I take my leave of the topic...

Nehalem Launch Emphasizes Upscale Drift Of Commodity Servers Question: When is a commodity server no longer a commodity server? Answer: When the system is so darn powerful it can run your data center. That's the deal with the latest crop of server CPUs, including Intel's Xeon 5500 unveiled on Monday, and AMD's upcoming six-core Istanbul. It's all of a piece with my theory that processing power has become ubiquitous, and figuratively free.

Software Vendors Get An F For Mobile Preparedness With most CIOs planning or building out enterprise-wide mobile strategies, you would think enterprise software companies would be rushing to lead the charge with suitably broad product roadmaps and strategies of their own.

What Intel's Nehalem Servers Mean To SMBs It might seem easy to dismiss Intel's new Xeon 5500 Series processors (code-named Nahelem) as expensive toys for high-performance computing and large enterprises.

Leave it to me to turn a camping weekend in the great outdoors into a serious shopping opportunity...check out the amazing (and amazingly affordable!) vintage jewelry I found this weekend, and the brilliant (if I do say so myself!) way I discovered to store it all...
My husband and I went with a few other couples on a camping trip in central Pennsylvania over the weekend, where we slept in tents, roasted marshmallows, and did all kinds of very un-NYC types of unwinding. On the way home, we passed a sign on the highway that said, "Antique Treasures," which meant, duh, we had to stop. "Treasures! We need those," I decided. And indeed, we found them. The little shop (called just Antique Treasures, 610-488-1545), owned by a mother and daughter, was overflowing with vintage everything, including an awesome selection of jewelry.
These 1960s-ish earrings were a serious score at $10--I plan to wear them with a bright turquoise silk dress to a wedding later this summer, and with plain old jeans and a white T-shirt, plus loads of other costume jewelry, as a go-to late summer outfit.
There was also a section devoted to ridiculously pretty vintage beaded collars that one of the owners, Ina, had found at a church sale. They were in impeccable condition and looked like they'd never been worn. I tried this pearl-encrusted one on choker-style and fell in love--did I mention it was also $10!?:
My smart husband was the one who suggested that it might actually look cuter worn flipped around--and hello, he was right! How perfectly on-trend is this when worn backwards?
They finally dragged me out of the store, and a few miles up the highway we made a shopping stop for the boys, to Cabela's, AKA hunting, fishing, and camping mecca. Lo and behold, I found myself the perfect vessel to stash my new jewelry purchases in! "Look!" I told the gang, "they have so many cool fishing Caboodles here!" After they recovered from hysterics and informed me that they're called, um, tackle boxes, they had to admit that it was a pretty inspired idea. Check out how organized my costume jewelry now is in its new home:
The price tag for this baby? $6.49, making this weekend officially some of my best bargain-hunting ever (not quite the type of hunting Cabela's customers usually have in mind, but hey...you can take the girl out of New York, but the New York out of the girl? Much harder).
And that, dolls, is how I enjoy the great outdoors...

Auburn coach Gene Chizik declined to comment on reports that the NCAA is investigating alleged improprieties involving the football program.
AUBURN — Auburn coach Gene Chizik declined to comment on reports that the NCAA is investigating alleged improprieties involving the football program.
"I'm not going to comment on speculation," Chizik said Wednesday. "It won't be a distraction to me. I'm just focused on the Iron Bowl."
The Birmingham News reported Wednesday that NCAA investigators have interviewed at least one assistant coach and several players this week as the Tigers prepare for their season final� Saturday against No. 2 Alabama.
The newspaper, citing an unidentified source, reported the investigation included but is not limited to the signing of running back Jovon Robinson, who was ruled ineligible amid allegations of academic improprieties.
The report said Auburn has not received an official letter of inquiry from the NCAA.
Yahoo! Sports also reported Wednesday that the NCAA has been investigating potential wrongdoing involving Auburn recruits, players, coaches and others.
That report says assistants Trooper Taylor and Curtis Luper haven't been allowed to recruit for several weeks.
The Yahoo report said the NCAA has investigated whether Wooddale physical education teacher Rhonda Wilkinson provided impermissible benefits to Robinson during his recruitment, including transportation to Auburn at least once. Wilkinson, an Auburn graduate, declined comment for that story.
NCAA spokeswoman Stacey Osburn said Wednesday that the governing body does not comment on current, pending or potential investigations. Auburn spokesman Kirk Sampson said the school had no comment on the reports.
Chizik already has been under fire during Auburn's 3-8 season. University President Jay Gogue has said he'll evaluate the program after the season, which ends Saturday.
In October, Chizik refused to discuss whether any coaches had been pulled off the recruiting trail.
"I don't have time for all of that," he said at the time.
Chizik also repeatedly has declined to address questions about whether he might be fired after the season. Chizik led the Tigers to the 2010 national championship, and the NCAA later said it had found no wrongdoing in an investigation into the recruitment of Heisman Trophy-winning quarterback Cam Newton.
Chizik parlayed that championship — Auburn's first since 1957 — into a contract worth about $3.6 million annually. He would be owed a $7.5 million buyout if he is fired on or after Dec. 1. He would be paid in monthly installments of about $208,000.
His new contract in June 2011 stipulated that he agrees to comply with Southeastern Conference and NCAA rules and disciplinary procedures. His previous deal would have allowed Auburn to suspend Chizik's salary if the program came under investigating by the university, the SEC or the NCAA for "alleged major rules violations or significant or repetitive violations."

Work can be the ideal environment for falling in love: you are in close proximity for a long period of time, you may have developed a good working partnership, and from there it is a short step to romance. However, workplace romance can present big problems. Dr. Romance helps you figure out the right and wrong ways to do it.
Dr. Romance on Dating in the Workplace
The problem of dating co-workers is what happens when the relationship doesn't work out. Still, many people find themselves attracted to people at work -- it's actually an environment that's similar to the college environment, which is the easiest place to date.
Research shows that the workplace is where the majority of couples meet. There's a reason for this: Unlike online dating, newspaper ads, singles events and speed dating, the office gives you a chance to actually get to know and even bond with a person before declaring your interest.
The reason so many people date in the workplace, even though it's often disastrous, is that it's easy.
Office Dating Do's and Don'ts
DO remember that you need your job, and act accordingly
DON'T get involved with a married co-worker, no matter how much you like each other.
DO keep your in-office behavior businesslike -- coworkers shouldn't be able to tell that you're dating.
DON'T share information with your coworkers about your dating situation. You'll become the subject of office gossip.
DO understand that, if the relationship has problems, you may wind up having to change jobs.
DON'T suddenly start dressing provocatively at work; it will alert your coworkers that something's going on.
DO remember your e-mails; phone calls, etc. are not private. If you must talk to your in-office inamorata, use your cell phone in a private space, where you can't be overheard, or talk in code.
DON'T allow yourself to be used by someone else in the office to get influence or information, and don't cuddle up to your boss in hopes of a promotion or raise.
The Unofficial Guide to Dating Again has many more guidelines to make modern dating fun, safe and successful.

It's been a while
I really have nothing to say..haha. I'm so boring!! Sorry readers. I'll try to do something interesting soon. Maybe I'll go skydiving or something. Or wrestle some alligators.
4 comments:
It's best if you wrestle the toothless variety, I think. ;)ReplyDelete
Glad that the rheuma isn't giving you trouble right now, and glad that you're staying busy without getting whopped over it. Don't worry about posting--we all have interludes where life takes over from the muse. It's nice to hear from you anyway, even if you haven't got anything in particular to tell.
I want to read ALL about it if you skydive, and not because I'd ever do it myself. I can't think of anything scarier than that, being of the heights-challenged variety.
Wishing you the best, Squirrel, as always.
So happy that are feeling good and staying busy. Let's hope it stays that way.ReplyDelete
I went skydiving years ago. If you get a chance, try it out. It is worth it!
Alligator wrestling for the win!ReplyDelete

It's not practical to try and have documents for each technology, as the explanations would be the same, and would constitute most of the text. The lexical part is by far the smallest part.

Have you ever walked into a situation where you know, you just know, people are hoping you fail? I've been there a number of times. My stomach knots up, my mouth gets dry and I set my listening and eye contact on laser focus. I become very still as I go into self-defense mode, deciding whether it's time for fight or flight. Then I start working out a plan; because like most people, I don't like to fail. At anything. And yet, of course, I have failed many times and in many ways. Sometimes it's because I've taken on too much, sometimes it's because I've taken on the wrong things and sometimes it's just beyond my control and sometimes I'm just plain wrong.
Jeremiah is in a similar situation, everyone is out to get him. Even his so called friends want vengeance. Yet his response is to put his trust in God, instead of working out a plan for himself. He trusts God to walk with him, to be his champion. In other words, not just to get him through this trial so he can come back to fight another day; he wants a full scale victory over his "frienemies." Not only that, he wants to see it!
I have to admit; sometimes it's so tempting to want to see the downfall of those who cause my pain. Who hasn't thought "I'd love to be a fly on the wall when ____ happens."? But who am I to judge? What do I know of their pain or plight? That's where I part company with Jeremiah. I pray often for strength to get me through situations where I'm feeling persecuted. I know in my own life that God has been my champion. Sometimes it has taken me a while to recognize it, but He has been my champion in ways small and large. I believe He is also in the life of the 'other', the false friend, the ones who hope I fail. Maybe their need is larger, more painful than mine. Maybe my failure is what God knows I need at the moment. Sometimes the unknowing is harder for me than the failure itself. That brings us full circle to trust. Jeremiah and I both trust in God as our champion. I admit sometimes it's hard to trust and sometimes I fail at it. I want to feel vindicated…but then again…what do I know? God knows.
I don't always need to know, all I need to know is God is my champion.

Truth be told I've been trying to get my mojo to sing loud and proud for an age, to middling success.
To get things hip hop moving along I spent a couple of days at the first ever Blogcademy in New York city. It was hands down one of the best things I've done to move my ideas forward in a really long time. The BEST. I think I may have a choir of mojo about to sing Hellalujah. It got me thinking about how we get our mojo's to sing…..I've jotted down some ideas at the bottom of this post if your needing a wriggle on.
Two gloriously affirming days hanging out with 29 other fabulous bloggers at the direction of three superstars of the blogosphere (and all things individual expression) Gala Darling, Nubby Twiglet and Kat Williams. And lets not forget the superstar of photography Lisa Devlin.
I was plunk in the middle of a
master mistress class and it was amazeballs!
The alchemy of hustle is all about living your joy and passion on your own terms and these women were rocking right out on that, they are alchemical hustlers in the truest sense of the title. They are tap dancing on the head of their passionate reason for being, and it is a glorious site to behold*. Unabashed, unadulterated full expression of self with the added bonus of making a very successful living from it. Is there no other holier grail than that? Well for me there's not, its my life's work.
The workshops style and delivery were perfect for the way I learn. Informal, packed with awesome content (from lessons learnt, tips, the basics, what works, what doesn't etc) and with loads of space for Q&A. I came away learning SO MUCH about all things blogging and how to make my blog fabulous. I am inspired with a game plan = ignited. And unexpectedly I learnt about the power of really living my mojo, singing from my own voice full time (not part). Over two days I soaked up the authentic voices of our teachers and it unconsciously washed over me and settled into my psyche. Seeing somebody else rocking it out prompts your subconscious to say "hey, why not join in"?
The other surprise gem has come from the community that has sprung to life and that is continuing to grow. A big nugget shared was the power of community, collaboration and support and the life these bring to our work, ideas, inspiration and selves. It's the relationships that make the difference. I am loving being a part of this community.
So if you'd like to get your mojo singing 'Hell to the Yeah' you could try a few of these:
- get clear about your joy/passion, what you want to do. this is a good read if your a bit murky.
- feel more, think less
- get your vision up where you can see it, it helps keep the main thing, the main thing. I wrote about how to make a vision board here
- start dabbling or dive right in, there will never be a perfect time (because there is no such thing as perfect) there is just now
- build your community – meet other like minded peeps for fun, inspiration and ongoing support. Veronica Varlow who attended Blogcademy wrote an awesome post on how to build community here
- get some steer and support on how to make it happen, I just found out about this fabulous woman/firestarter. want more than just a book/online resource? a life coach can be an incredible resource for creating change or a mentor could be your thang
- make self care a priority, good food/sleep/balance/water/friends/fun are all part of the equation
- learn from the best, ask questions from those that have done it……soak it up (trust me it is priceless gold to be in conversation with people who are successfully singing from the top of their mojo's lungs – see Gala, Nubby and Kat's links above).
- be yourself, its a fruitless task being anybody else
What gets your mojo singing loud and proud?
*My description of these fabulous woman may to some sound a tad gushy, it is not. I write with authenticity and honesty on the things and people that genuinely inspire and motivate me (and shining a flood light on powerful woman is a good thing, I feel). Seeing individuals doing their thing/joy and being truly themselves is powerful, it is a massive agitator of change and enhancer of mojo happiness. I found that out this weekend in bucket loads.

This article is from the archive of our partner .
I must first admit to some bias. I approached Girls, HBO's new series about the aimless youngs of Brooklyn, with more than a little snide skepticism. Here is a show that purports to be a very realistic depiction of a particular experience — young broke post-collegers trying to do something creative in an exciting yet daunting city — that I myself lived very recently. And here was Lena Dunham, the show's creator/star/writer/director, a girl with a sense of humor not unlike my own, and ambitions — blogs! TV scripts! alt comedy! — that are (were?) basically my ambitions. For me, this show comes jam-packed with things to dislike, to take personal affront to, to stir the battery acid curdle of dark jealousy within me, only to have it manifested externally as a kind of haughty eye-rolling.
Meaning, it's easy to outwardly harsh on Girls for one glaring reason: Though the show is about young women struggling in New York, those young women are all played by scions of veritable New York creative royalty. Dunham is the daughter of the well-known artist Laurie Simmons, who let her daughter shoot her breakthrough film Tiny Furniture in the family's stylish TriBeCa apartment and who sent that daughter to the $33,000/year Saint Ann's School in Brooklyn Heights. Dunham knows from broke-assery how, exactly? And her costars! There's Allison Williams, daughter of dashing but funny anchorman Brian Williams. There's Zosia Mamet, whose dad David is, y'know, only one of the most important playwrights (and, arguably, filmmakers) of the past century. And finally there's Dunham's old Saint Ann's chum Jemima Kirke, a queen bee of downtown Manhattan and the daughter of a member of the band Bad Company. She's friends with Paz de la Huerta! So, you get the picture. What business do any of these people have talking to us, regular non-royalty folk, about the poor young experience in the big bad city?
That was the righteous anger I could muster about this show in order to mask the seething "Why did HBO just hand her a show and not me???" envy and rage that roiled beneath my faux-principled exterior. And I do still think there's some merit in that argument. Though, to be fair, this may ultimately not be the fault of Dunham and co. The whole "this is very realistic" trope could have come from HBO marketing. Maybe Dunham just wanted to make a funny show that was personal to her, regardless of whether it rang with precise truth for anyone else. And you know what? Goddammit, if she hasn't done just that.
Yes, I admit it. I've now seen three episodes of Girls and I've liked each one more than the last. I'd seen the pilot months ago while still in my haze of self-loathing anguish over the mere existence of the series and, going in with all that preloaded disdain and everything, promptly hated it. Just dismissed it, was determined to stand obstinate in the face of the huge raft of praise carrying the show to its premiere (this Sunday at 10:30). But then I rewatched the episode and the subsequent two this week and, to my great surprise and strange dismay, I found myself laughing at the show's specific humor, warmed by its easy rhythms and, yes, eerie sense of familiarity. Dammit, Dunham!
The show's setup is relatively lo-fi: Dunham plays Hannah, a moony 24-year-old with a moldering English degree who, in the pilot, is finally cut off from her family's modest bankroll. This triggers a mild tailspin into panic and a "what am I doing with my life" desperation that many of us felt at that age and, sigh, have felt since. There's little cliched or stagey about Hannah's charmingly selfish, indulgent reaction to her defunding — sure she goes to her visiting parents' hotel room high on opium tea, which we would never do, but c'mon, this is a TV comedy, silly things need to happen. Dunham is pretty adept at gently making fun of her character, and by extension her actual self, and by bigger extension an entire generation of kids who assume themselves, each and every one, destined for and, more importantly, deserving of great, fun, cool, respectable careers and lives. There's a frustrating narcissism running through Hannah — her reaction to people getting upset is to usually ask "Are you mad at me?" — but it's probably frustrating mostly because it speaks to so many embarrassing truths about our own selves. We all, not just millennial coastal kids, see the rest of the world as the supporting dramatis personae to our own protagonist. Hannah is just a little worse at hiding that fact. It's a character flaw that's relatable and almost sweet, rather than grating and alienating, the way I assumed it would be.
Besides money woes, there are of course romantic entanglements to be dealt with. Girls has a frank but not explicit approach to sex, and while Katie Roiphe might, gulp, have a point about the sex being perhaps a little too awkward and unpleasant, there's a grainy realism to it that keeps it firmly within believable bounds. I like that this show doesn't go all New Girl and desexualize its characters, nor does it fall prey to executive producer Judd Apatow's baser instincts and overplay the filthy talk. The sex conversation actually feels just about pitch-perfect, just bawdy enough to elicit a laugh, but not so over-the-top as to enter into groany Stiffler territory. Hey, those girls talk like people do, like people do about sex! It feels way more revolutionary than it should.
Hannah is having odd, borderline debasing sex with a rat-faced lout named Adam (Adam Driver), who is, regrettably, pretty attractive in his loutishness. It makes sense why Hannah's friends would be repulsed by him and why Hannah would keep going back. He's an asshole, but he can be a kind asshole, an almost caring asshole, and so his asshole-ishness is endured. It's a stilted kind of relationship that most certainly exists in the real world — either we've seen our friends do it, or we've been the sadsack ourselves, quietly but desperately wishing for the person across the couch to pull us in closer. Meanwhile, Williams' Marnie, an art gallery assistant who's mostly got her shit together, is dating a sweet boy named Charlie (Christopher Abbot) whose sweetness and gentleness perpetually infuriate her. "He's so busy, like, respecting me, you know, that he looks right past me," Marnie says in one spot-on exchange. Hannah is mostly ignored by her prototypical jerky guy, while Marnie is overly doted upon by her enlightented beta male beau. They can't win! But really, how many people can at that age?
Kirke and Mamet play the two more comical characters, Kirke a stylish yet blowsy prodigal friend, Mamet her uptight Sex and the City-obsessed college student cousin who lives in Nolita (everyone else is in Greenpoint) on her parents' dime. Though initally a bit roughly drawn, both characters become more shaded and less strained over the course of the first three episodes. Mamet in particular, especially in one lovely scene in which she and Hannah discuss trashy reality shows and HPV, exhibits such pleasingly natural smarts that we hope they soon completely abandon the mean mocking tone she's addressed with and just let her be her, as repressed and dorky, but naturally so, as that might be.
I feel forced into mentioning Sex and the City now (the show self-consciously throws it right out there in the first episode), which is a little annoying. Because while, yes, Girls is a show about four women in New York City same as Sex and the City was, that earlier show is an insane cartoon compared to what Dunham has made. Which isn't to say that Girls is necessarily better — Sex and the City was then and remains still a fine television show — just that its aims and approach are entirely different. SATC was fantasy and fable, with a few bits of relatable relationship stuff thrown to the commoners like chum. Girls is something else; it's a very particular, very of the moment dissection of mundanely funny minutiae, of boredom and anxiety in these brownly grim times. Though I guess it's possible the difference really is merely generational — the rich late '90s gave us Sex, while the wobbly '10s give us Girls, a witty and occasionally touching glimpse into our immediate neighbors' lives. They've got something here, it just remains to be seen how big a thing it is.
Who knows, it could be that soon enough young women the nation over will be saying they're "such a Hannah" or "totally a Marnie." Maybe fabulous is officially out. Maybe the new aspiration in these punishing times is, simply, to aspire.

You won't see it in television ads about retirement. You won't hear it at investment conferences. You probably won't read much about it in newspapers or personal finance magazines or on the Internet.
And yet the biggest threat we face to our financial security in retirement may be the massive drop-off in our own capacity to manage our investments as we age.
Physiological changes in the aging brain can cause significant declines in our ability to process new information, handle risk or react appropriately to market events.
They make older people more vulnerable to scam artists, of course, but they also make it much harder for the elderly to make good investment decisions.
And it's not just about dementia, whose likelihood doubles every five years as we age. A large percentage of people who live into their 80s — and there are more and more of them all the time — will suffer some form of cognitive impairment.
I know this is something most of us don't want to think about. But there are steps you can take earlier — probably in your 60s — to protect yourself, your wealth and your family.
The roadmap of decline in investing ability is rooted deep in human biology, and here I need to make a brief and, I hope, painless foray into the physiology of the human brain.
"A lot of the cognitive functions or processes involved in financial decision making are located in the frontal cortex," said Dr. Joe Verghese, a professor of neurology at Albert Einstein College of Medicine and chief of geriatrics at Einstein and Montefiore Medical Center in New York.
Because of the cortex's predominance throughout much of adulthood, we get better and better at investing until we hit our mid-50s, when we begin a slow, inexorable decline.
Why? As we age, the limbic system, one of the oldest structures in the human brain and the seat of primal emotions like fear and greed, becomes more and more powerful.
"As we get older, our prefrontal cortex has a more difficult time tamping down emotions, and it may have more difficulty putting complex information into context," Michael S. Finke of Texas Tech University told me.
Around 70, wrote Alok Kumar of the University of Miami, investment skill "deteriorates sharply" and investors' "ability to handle risk declines."
That can lead to panic selling, such as the kind we saw in 2008-2009. With hindsight, buy and hold was the way to go. But try telling that to a 75-year-old widow who watched a third of her retirement savings go up in smoke.
"Investors who are carrying market risk by holding a large amount of stock may be more susceptible to cognitive-driven underperformance," Finke told me in an interview.

This twiki documents the most important steps of the Drell-Yan cross section measurement. It is intended to familiarize you with the technical aspects of the analysis procedure. At the end of each section there is a set of questions and exercises. Note, the software and samples evolve very frequently so some parts of the page will get obsolete soon!
Current latest MC generation is 42X Summer11
cmsrel CMSSW_4_1_3 cd CMSSW_4_1_3/src cmsenv addpkg ElectroWeakAnalysis/Skimming cvs co -d ElectroWeakAnalysis/DYskimming -r V00-00-05 UserCode/Purdue/DYAnalysis/Skimming scram b cmsRun ElectroWeakAnalysis/DYskimming/PATTuple/test_cfg.py
Exercise 1:
Q1: Do you think the list of signal and background samples mentioned above is complete for the Drell-Yan cross section measurement in the region 15-600 GeV invariant mass? (You need to think not only about physics processes but also about kinematic region of the sample generated)
Q2: Using the DBS tool mentioned above or a command line equivalent find all the MC samples relevant for the Drell-Yan cross-section measurement for Summer11 production, example:
find file where file.tier=GEN-SIM-RECO and site=srm-dcache.rcac.purdue.edu and dataset like=*DYToMuMu*Summer11*
Q3. (might be advanced, if you fails ask me) Port the above skimming code to 42X: you need this, because 41X and 42X releases are incompatible
Q4: Produce a PAT-tuple
More PAT-tuples can be found here: /store/user/asvyatko/DYstudy/dataAnalysis11//PATtuple/ (you can use signal and Data only for now)
Since the event size even for PAT is quite big, we usually perform one more skimming step and store our data in form of ntuples. The input for ntuple-maker is PAT tuple (however, with some gymnastics you can run on GEN-SIM-RECO or AODSIM)
cd $CMSSW_RELEASE_BASE/src cvs co -d Phys/DiMuonAnalyzer UserCode/Purdue/DYAnalysis/NtupleMaker scram b cd Phys/DimuonAnalyzer cmsRun test/test_cfg.py
For mass ntuples submission you need to use batch farms. Use scripts provided in the /ntuple directory to do that:
./Ntuples.csh ./Submit.csh
Note: before submitting you need to change the input/output directory parameters and the global tag in the batchJob.pl script:
# configure here $isMC = 1; # 0 = MC, 1 = data $trig = "HLT_Mu11/Data"; $ntpdir = "/user/h/hdyoo/DYstudy/dataAnalysis10_39x/PATtuple/"; $outdir = "/user/h/hdyoo/DYstudy/dataAnalysis10_39x/Ntuple/"; $workdir = "/afs/cern.ch/user/h/hdyoo/scratch1/DYanalysis/NtupleProducer/src/Phys/DiMuonAnalyzer/ntuples"; $gtag = "GR_R_39X_V6"; # data #$gtag = "START39_V9"; # mc
to your desired directories and the latest global tag.
Exercise 2:
Q1: Try to produce ntuple
Hint: spot all the errors, they might be related to global tag, REDIGI version (for MC)
Q2: Find the invariant mass branch and inspect it
Once the ntuples are ready, one can proceed to the actual physics analysis. The first step of every analysis is the event selection. Currently, we use the so-called cut-based approach to discriminate between signal and background. For more on event selection please read chapter 3 in the analysis note CMS-AN-11-013. Before starting to run a macro, set up the working area. Find all the necessary scripts in:
UserCode/Purdue/DYAnalysis/NtupleMaker/interface UserCode/Purdue/DYAnalysis/NtupleMaker/ntuples
and precisely follow the recipe below preserving folder structure recommended in the recipe:
1. copy the Ntuples in rootfiles directory, splitting by trigger path used at the level of skimming (as we might use a combination!): e.g. rootfiles/HLT_Mu15/ 2. modify the createChain.pl file cd rootfiles vim createChain.pl change this to the full path to your rootfiles directory: $dir = "/work/asvyatko/Work/DYanalysis/dataAnalysis10/analysis/rootfiles"; choose the trigger scenario you wish to use: $trig = "HLT_Mu15"; // trigger name (directory name) Run the shell script: ./Chains.csh then all chain_* files will be created in the roorfiles directory.
cd .. cvs co -d ControlPlots UserCode/Purdue/DYAnalysis/AnalysisMacros/ControlPlots cd ControlPlots #note: for the sake of convenience add the alias for this directory in your ~/.profile, like: #CONTROL_PLOTS_DIR=/whatever.is/the/absolte_path #export CONTROL_PLOTS_DIR
Before running the macros, we need to fix few things which are changing frequently for our analysis:
To produce the invariant mass plot do use the analyse2.C macro, which calls the TSelector for the DY analysis (called EventSelector):
root -l analyse2.C
The macro allows to run on multiple cores.
By performing minor changes inside the EventSelector one can calculate the efficiency weighted invariant mass distribution (which is used to estimate the corection factor as a function of invariant mass). Inside the EventSelector.C set
#define CORRECT_FOR_EFF true <- change to true if you want to use it for efficiency correction estimation
To produce dimuon kinematic distributions run
root -l TransMomentum.C++ root -l Rapidity.C++
To produce other control plot (for all the event selection variables used in the analysis, as documented in the note), use:
root -l ControlPlots.C++
There are few macros that help us to optimize the cuts. These macros calculate the statistical significance and the uncertainty on the cross-section. Statistical significance is defined as :
S = N_sig/sqrt(N_sig+N_bkg) and normally determined from MC. As you can infer, it scales with luminosity as ~sqrt(Lumi). There are other definitions of significance used in the analyses sometimes (see for instance CMS-TDR). To run, check out just two additional macros (I assume you didn't leave ./ControlPlots directory)
cvs co UserCode/Purdue/DYAnalysis/NtupleMacro/AsymmetricCutStudy/OfflineSelection.C cvs co UserCode/Purdue/DYAnalysis/NtupleMacro/AsymmetricCutStudy/graphStats.C root -l OfflineSelection.C++ root -l graphStats.C++
The first macro will create a txt file with an per mass bin values of signal and background. The second macro will histogram the output. These macros are adjusted to optimize the acceptance cuts, but with minimal changes it can optimize any other cut we use, and it is possible to change style to conform with the rest of plots in the note.
Note: root doesn not create output directories by itself so you should create a corresponding directory for output txt files like:
mkdir my_output_dir_for_macro1
Q1: Check data/MC agreement for each plot, look for discrepancies.
Checkpoint1 With the macros described above you should be able to *reproduce* following plots from the CMS-AN-11-013: 1,3-14, 17-29,51.
Note: for the 23,25-29 macros have different style and were produce with PU sample.
Note: plots 20-22 are reproducible by optimization macros but have different style.
Another constituent of the cross-section measurement is the acceptance.
Below are some additional details on the acceptance calculation which might be necessary if the procedure will change.
We use POWHEG NLO acceptance, see all the relevant formulas in this talk (the updated version), see slide18 for acceptance definitions and refer to earlier talks. Di\ue to the intrinsic discrepancies in the modeling between the POWHEG and FEWZ we correct the Z kinematics. For that, we extract the weight maps from POWHEG at NLO and from FEWZ at NNLO (to be more specific it is at NNLO below 40 GeV and NLO otherwise, as the effect of higher order corrections is negligible at the higher masses). The weight map is essentially the ratio of double inclusive cross-sections extracted from POWHEG and FEWZ per PT-Y bin (PT, Y refer to Z kinematics, which is identical here to dimuon kinematics, our final aim). Details on the re-weighting technique are also in the linked presentation.
How to run:
To setup area do:
cd $CMSSW_RELEASE_BASE/src cvs co -r V00-09-11 SUSYBSMAnalysis/Zprime2muAnalysis (38x analysis) # for 41x or higher, use V00-10-09 cmsenv SUSYBSMAnalysis/Zprime2muAnalysis/setup.csh # This last command checks # out other packages and # executes scramv1 b to # compile everything. cvs co UserCode/Purdue/DYAnalysis/AcceptanceAdam #rearrange stuff a little bit cp UserCode/Purdue/DYAnalysis/AcceptanceAdam/* .
//description to be added - I will ask Adam. But actually we switched to Purdue ntuples so this section is obsolete....
Inspect the countxsec.py script in the directory. What it does is following:
It takes hard interaction ntuple produced on the previous step, which contains the gen level information about the hard collision and produces the 2D histogram in the bins of dimuon Pt-Y for each mass bin, as well as 3 auxiliary histograms with mass spectrum pre-FSR (after acceptance cuts, marked with 'num'). The only part which is expected to be configured frequently is the mass, Pt, Y binning everything else is fixed. (Note that right now the input can also be set to Purdue ntuple!!)
To test the script locally on few hundred of events do:
python countxsec.py --s 1667 --n 20000000 --w 1.0 --sg DYM1020/a2_2011/AcceptanceFromPAT_2011_mapcfg-pat_9_1_WaI/zp2mu_histos.root
To submit the batch script on full statistics, use the farmaout scripts and the local batch system:

The submission directory should not exist, otherwise you get an error.
Note: you obviously do not want to recalculate the weights, numbers of events for each stepwise DY sample. For Summer11 the numbers are already available here: /UserCode/Purdue/DYAnalysis/AcceptanceAdam/commands_XSEC.txt
But for Fall11 I will have to recalculate it and update the corresponding file.
To make weights one needs to run following:
python makeweights.py
The weights referred here are the FEWZ-POWHEG cross section ratios per Pt-Y bin (see one of the Adam's presentations). What the script does is essentially following: it takes the POWHEG Pt-Y maps produced on the previous step, takes the FEWZ Pt-Y maps (which are produced by Alexey and usually latest are found here: https://twiki.cern.ch/twiki/bin/view/CMS/EWKDrellYan2011, the file starting with map2D_*.root), and just divides it bin by bin using the my_divide function (this is a clopper-pearson divide).
Complications: there is a set of parameters and input files which is configures inside the script.
First of all POWHEG input files:
## ADAM for NNLO #Get the files with POWHEG maps with fine Pt binning fileIn10fine=ROOT.TFile("DYM1020/xsec04w1_newFine/powheg_xs_full_04_2011.root") #coarse Pt binningfileIn10 = ROOT.TFile( "DYM1020/xsec04w1_new/powheg_xs_full_04_2011.root") #fine Pt binningfileIn20fine=ROOT.TFile("DYM20/xsec04w1_newFine/powheg_xs_full_04_2011.root") #coarse Pt binningfileIn20 = ROOT.TFile( "DYM20/xsec04w1_new/powheg_xs_full_04_2011.root") fileIn200 = ROOT.TFile( "DYM200/xsec04w1_new/powheg_xs_full_04_2011.root") fileIn500 = ROOT.TFile( "DYM500/xsec04w1_new/powheg_xs_full_04_2011.root") fileIn1000 = ROOT.TFile("DYM1000/xsec04w1_new/powheg_xs_full_04_2011.root")
There are multiple input files, because we use STEPWISE DY samples, they are split in generator mass. On the other hand, we fix the Pt-Y binning on the previous step, so that if we decide to play around with binning we need to provide a different input file (you can see fileIn10fine and fileIn10 for instance). The parameter finePtBins controls the number of first mass bins which will use fine binning.
Secondly, FEWZ input files: this are also hardcode inside the script, because multiple versions exist (differing by Vegas integration precision and NNLO/NLO order). The parameter nnloInBins controls the amount of first mass bins in which we have NNLO.
The output of the script is DYMoutput/weights_stepwise_precision10-5_fine12.root - the file with histograms with weights and errors.
Inspect the countcorracc.py script in the directory. What it does is following:
To test the script locally on few hundred of events do:
python countcorracc.py --r DYMoutput/fewz_powheg_weights_stepwise_2011_fine12.root --o fewz_powheg_corracc_2011 --n 5.78216 --s 3320.0 --e 9630633.0 --l 15 --h 20 --sg DYM1020/a2_2011/AcceptanceFromPAT_2011_mapcfg-pat_9_1_WaI/zp2mu_histos.root
Note that again one has to run a separate job on each of the stepwise DY samples. And the weights, event numbers and cross section passed as an argument would have to be different for each sample.
To submit a batch job do:
cd /home/ba01/u112/aeverett/scratch_rcac/20112011/DYM1020 farmoutAnalysisJobsPyList.sh bob $CMSSW_BASE /home/ba01/u112/aeverett/scratch_rcac/20112011/countcorracc.py --skip-srmcp --submit-dir=$PWD/corracc_stepwise_coarse7b --input-files-per-job=1 --assume-input-files-exist --input-file-list=$PWD/inFileList.txt --input-dir=$PWD/ --python-arguments=" --r /home/ba01/u112/aeverett/scratch_rcac/20112011/DYMoutput/fewz_powheg_weights_stepwise_2011_coarse7.root --o fewz_powheg_corracc_2011 --n 5.78216 --s 3320.0 --e 9630633.0 --l 15 --h 20"
The tricky part about this script is:
One needs to configure pT and eta cuts for each muon in the script. This is done very easily in two places:
if input_is_MC: from UserCode.Examples.inclusiveMuonPlotsGENSIM_cfi import makeInclusiveMuonPlots; commonInputs = cms.PSet( muons = cms.InputTag('cleanPatMuonsTriggerMatch'), particleSrc = cms.InputTag('prunedGenSimLeptons'), #genParticles dilepton_src = cms.InputTag('dimuons'), #('dimuons'), #('dyz'), primaryVertices = cms.InputTag("offlinePrimaryVertices"), weight = cms.untracked.double(1.0), eta_acc1 = cms.untracked.double(2.4), eta_acc2 = cms.untracked.double(2.4), pt_acc1 = cms.untracked.double(15.0), pt_acc2 = cms.untracked.double(10.0), mother = cms.untracked.int32(23),#Z: 23, ZPrime: 32 daughter = cms.untracked.int32(13), daughterStatus = cms.untracked.int32(1), )
And here:
loose_cut = 'isGlobalMuon && isTrackerMuon && ' \ 'pt > 10. && ' \ 'abs(eta) < 2.4 && ' \ 'abs(dB) < 0.2 && ' \ '(isolationR03.sumPt + isolationR03.hadEt) / pt < 0.15 && ' \ 'globalTrack.hitPattern.numberOfValidTrackerHits > 10 && ' \ 'globalTrack.hitPattern.numberOfValidPixelHits > 0 && ' \ 'globalTrack.hitPattern.numberOfValidMuonHits > 0 && ' \ 'numberOfMatches > 1 && ' \ 'globalTrack.normalizedChi2 < 10 ' # + trigger_match
To configure the trigger path for trigger match:
trigger_match = ' && (' \ '!triggerObjectMatchesByPath("HLT_Mu15_*").empty()' \ ')'
To calculate the acceptance as a function of invariant mass:
python AcceptanceFromPAT_a2_mapcfg.py
Next, produce histograms for invariant mass and Z/lepton kinematics you will use to calculate the acceptance:
root -l macroAcceptance.C
To draw the plots execute:
root -l macroDrawHwidongAcc.C
Weight map producer uses the FEWZ acceptance as the input, find all the macros here: /UserCode/ASvyatkovskiy/FEWZ_scripts,
to work one needs to do:
cd $RCAC_SCRATCH/ #better to do it on scratch cp -r /home/ba01/u115/asvyatko/TEST_FEWZ/FEWZ_2.0.1.a3/ YOUR_FEWZ_WORKING_DIR cvs co -d TMP /UserCode/ASvyatkovskiy/FEWZ_scripts cp TMP/* . rm -r TMP
To produce the cross section in mass bins run
python nu_createInputFEWZ_mod_multiple.py
Note: before running you need to adjust the order of calculation and the input/output directories and also the PDF set you want to use, which is all done in the top of the script:
#input: binning file, pdf sets, order, number of processors and path to working dir mass_cuts = open('input_massesPlus.txt','r') pdfsets = ['MSTW2008NLO'] #['CTEQ66','CTEQ10','NNPDF20','MSTW2008NLO'] order = 'NLO' nprocs = 1 path_to_wd = '/scratch/scratch95/a/asvyatko/NU_FEWZ/WorkingDir_NLO_400Plus' masses = mass_cuts.readlines() mass_cuts.close() pattern = r'(\d+\.\d*|\.\d+)(d0)' pattern2 = r'(\'\s\d?)' pdf_pattern = r'(CTEQ66|CTEQ10|NNPDF20|MSTW2008.*O)'
to get the output of the jobs use corresponding get-output scripts:
python nu_getOutputFEWZ_multiple.py
Which requires analogous adjustments before use:
#input: binning file, pdf sets, order, number of processors and path to working dir mass_cuts = open('input_massesPlus.txt','r') pdfsets = ['MSTW2008NLO'] #['CTEQ66','CTEQ10','NNPDF20','MSTW2008NLO'] order = 'NLO' nprocs = 1 path_to_wd = '/scratch/scratch95/a/asvyatko/NU_FEWZ/WorkingDir_NLO_400Plus' run = '' acc = '' #acc21_, acc24_
After the maps are ready and saved in the root file, you can proceed with corrected acceptance calculation. Before that, review the maps to check if there is nothing strange:
root -l Map2D.C
Q: Analyze 2D histograms for maps
If you do not have time to produce the maps, you can use what we have, kindly read the description in the README file and use the root and txt files on the following webpage:
If everything looks reasonable (no very large weights, no pronounced asymmetries), continue with corrected acceptance (before doing that make sure to carefully review this talk by Adam):
python countxsec.py DYM1020_single_tuple.root DYM20_single_tuple.root #you can find test root files here #/store/user/asvyatko/DYstudy/AN11_013_archives/TestAcceptanceAdam/ #or use the PAT tuple produce on the step1 python makeweights.py powheg_xs_full.root fewz_xs_full.root python countcorracc.py --sg=DYM1020_single_tuple.root,DYM20_single_tuple.root -r fewz_powheg_weights.root
Each next step uses the output of the previous step. Firstly we calculate the PT-Y dimuon kinematics map, then we calculate weight for FEWZ-POWHEG reweighting and finally we calculate the corrected acceptance. Note: the k factors are equal to 1 by default but should be readjusted in case one uses NLO FEWZ maps (rather than NNLO)
Finally, there are various plots used to estimate the FEWZ-POWHEG discrepancy for various trigger scenarios as well as NNLO-NLO discrepancy for within a given generator and a given PDF set. These plots can be reproduced using the following macros:
cp /UserCode/Purdue/DYAnalysis/AnalysisMacros/ControlPlots/Acceptance.C $CONTROL_PLOTS_DIR #Acceptance macro isn't in current dir :-/ , copy it cd $CONTROL_PLOTS_DIR root -l Acceptance.C
inside this macro, you can uncomment what you need to plot and also adjust the input PDF sets as well as orders.
Checkpoint2 With the macros and scripts described in the step4 section you should be able to *reproduce* following macros from the CMS-AN-11-013: 2,30-38,61-63 and tables: 5-10, 21-24
The details on the factorization and the application of correction factors are documented here , and can be found in this talk. With the current factorization scheme we measure four following efficiencies:
addpkg CommonTools/ParticleFlow V00-02-07 addpkg CommonTools/RecoAlgos V00-03-13 addpkg DataFormats/PatCandidates V06-04-18 addpkg MuonAnalysis/MuonAssociators V01-13-00 addpkg MuonAnalysis/TagAndProbe HEAD addpkg PhysicsTools/Configuration V00-10-16 addpkg PhysicsTools/PatAlgos V08-06-38 addpkg PhysicsTools/PatExamples V00-05-22 addpkg PhysicsTools/SelectorUtils V00-03-17 addpkg PhysicsTools/TagAndProbe HEAD addpkg RecoMuon/MuonIdentification V01-19-00 cvs co -d TagAndProbe UserCode/ASvyatkovskiy/TagAndProbe
cd TagAndProbe cmsRun tp_from_aod_Data_newofficial.py
cmsRun fitMuonID_data_all_2011.py
After familiarizing yourself with the TagAndProbe package, you need to produce the muon efficiencies as a function of pT and eta. You do not need this in the analysis, but rather to understand if everything you are doing is correct. After you are done with that, produce the 2D efficiency pT-eta map (it is alredy produced in one go when running fiMuonID.py). To do that use the simple root macros (adjust i/o, not user friendly yet!):
root -l idDataMC_4xy.C root -l triggerMuonDataMC_4xy.C
And to produce 2D efficiency maps and correction factors do:
root -l perBinTable.C
The final step here is to produce the efficiency as function of invariant mass and the efficiency correction factor as a function of invariant mass.
cvs co UserCode/Purdue/DYAnalysis/AnalysisMacros/Correction root -l efficiencyMass_newTmp.C root -l correctionMass_newTmp.C
Note: you need to produce all the correction 2D maps on 2 previous steps, if you haven't succeeded you can use what we used for publication, txt files are located here:
Checkpoint3 With the macros describe in the step5 section it is possible to reproduce the following plots from the CMS-AN-11-013 note: 15-16, 39-42 and tables 11-12
Note: plot 40 was produced with LKTC method, code for which is currently not public and not possible to be retrieved from the authors. Currently (2011 data) the result is consistent with that obtained with Tag-And-Probe.
There are various methods employed to estimate the QCD background in a data-driven way (QCD is currently the only background estimated not from MC). The most important are the template fit method and the weight map method: carefully read chapter6 of the CMS-AN-11-013 for more details on the methods.
Reweighting method. First of all, read the quick description (in addition to what is written in the note) and also see this presentation .
cd $CONTROL_PLOTS_DIR cd .. cvs co -d ControlPlots UserCode/Purdue/DYAnalysis/AnalysisMacros/QCDEstimation
There are few steps in this method. First of all, create a pT-eta weight look-up table indicating probability of a muon to be isolated as a function of muon pT-eta:
cd ControlPlots root -l WeightMapFiller.C
The next step is to view the map, and to test it on the sample of dimuons and single muons:
root -l testWeightMapDouble.C root -l testWeightMapSingle.C
Other methods used for the QCD background estimation in the note are the SS/OS pair method and template fit method (carefully read the note on the description!). For the SS-OS method, which uses the discriminative power of the isolation variable, considering classes of events having 2, 1or 0 isolated muon. You can get the plot by running:
cd $CMSSW_RELEASE_BASE/src cvs co UserCode/ASvyatkovskiy/QCD_Background cd UserCode/ASvyatkovskiy/QCD_Background root -l bgSS_OS.C
As for the template fit method:
root -l .L auto_fits.C; fitAll() #It needs input parameters - the important ones are #bool etaBelow1_2 = false; #bool fitFirstMu = true; #bool singleMu = false;
Note: the original input files can be found at:
Checkpoint: this macros will allow one to reproduce the plots 45-48 from the note as well as tables 13-15 from the note
We estimate QCD background using ABCD method in order to improve our systematic uncertainty on the background estimation. ABCD method is very simple.
1) choose 2 variables: assume two variables are independent
2) assume the fraction should be same if there is no correlation: N_A / N_B = N_C / N_D
3) In our study, use two variables: sign of muon pair, muon isolation
4) QCD fraction in each region has a dependence. We produce the correction factor for each region: B, C, D
5) Produce N_B, N_C, N_D from data sample, and estimate N_A from them at the end (applying the correction factors)
In UserCode/Purdue/DYAnalysis/AnalysisMacros/ABCDmethod
QCDFrac.C: to produce correction factors for each region
ABCD2vari.C: to produce the ABCD results. The correction factors from the QCDFrac.C are plugged in this macro as an input.
We employ the so-called e-mu data driven background estimation method. See the following comprehensive talk for more details on the method. Currently the procedure to apply this method consists of 2 steps:
1) produce the root files with histograms
2) run the macros on the root files produced
For both steps one needs to check out the following tags:
V00-05-00 MuonAnalysis/Examples
The highleted tags are important for step2).
Following is the description of how to produce the root files.
The mother script file is Zprime2muAnalysis/test/DataMCSpectraComparison/histos.py
Instructions related to this script file are at
The short instruction is this:
python histos.py submit testing no_data
or when you are ready
python histos.py submit
Wait for root files to be done. Currently it is configured to have histograms with selection marked 'VBTF' as what we have in DY2011.
Below I describe the step2 in detail. Check out addtional macros, and copy them to your working directory:
cvs co UserCode/Purdue/DYAnalysis/AnalysisMacros/TTbarEstimation cp UserCode/Purdue/DYAnalysis/AnalysisMacros/TTbarEstimation/* cd SUSYBSMAnalysis/Zprime2muAnalysis/test/DataMCSpectraComparison
Make sure the paths to datafiles inside the macros are pointing to the location of the root files you have produced. To produce the control plots for emu and mumu mass spectra use
python emu_basichists.py
To produce the correction factors run:
python emu_corrfactors.py
And finally, the MC expectation vs. data driven method prediction plots are produced with:
python emu_prediction_plots.py
A good agreement between data and MC for both the mumu and emu spectra is necessary for a method to work reliably.
Unfolding is applied to correct for migration of entries between bins caused by mass resolution effects (FSR correction is taken into account as a separate step). For use in the Drell-Yan analysis, the choice for unfolding is matrix inversion. Provides a common interface between channels for symmetry and ease in combination and systematic studies.
To do any unfolding with MC, this requires 3 things:
First, one can do some exercise, for that use script that demonstrates how the unfolding/fore-folding object works.
cvs co UserCode/kypreos/drellYan2010/unfolding cd UserCode/kypreos/drellYan2010/unfolding/ source setup.sh
root -l test/testExpo.C++
To get back the pulls:
root -l test/testPulls.C++
The macros in the note are produced with the following:
cvs co /UserCode/Purdue/DYAnalysis/Unfolding
1. To rpoduce the response matrix:
root -l unfoldingObs.C
2. To produce the unfolded yield plot do
root -l yield.C
Checkpoint7 with this macros one should be able to reproduce the plot 49-50 from the note and Tables 17-18 (note, the table 18 uses the background yield result from the background section)
The effect of FSR is manifested by photon emission off the final state muon. It leads to change of the dimuon invariant mass and as a result a dimuon has invariant mass distinct from the propagator (or Z/gamma*) mass.
For our analysis we estimate the effect of FSR and the corresponding correction by estimating the bin-by-bin correction in invariant mass bins. Which is done by comparing the pre-FSR and the post-FSR spectra. The pre-FSR spectrum can be obtained by requiring mother of muon to be Z/gamma*, post FSR spectrum is when the mother is whatever.. The corresponding plots in the note are: 52-55 they all can be calculated with the information avaialble in the ntuple using
cd $CONTROL_PLOTS_DIR root -l InvMassFSR.C++
To get the FSR histograms one needs to turno on calculateFSR flag on.
Checkpoint: this macro will allow one to get plots 52-55 from the note
There are various sources of systematics affecting our analysis: the PDF, theoretical modeling uncertainty, efficiency estimation uncertainty, background estimation, unfolding etc.
For the background estimation, with the data driven method we estimate the systematic uncertainty as the difference between the result obtained with the method and that
expected from MC per mass bin. Corresponding numbers are obtained with the emu_prediction_plots.py
macro (see the recipe in the step 6 section).
PDF uncertainty estimation. The recipe for the method currently used (step by step).
Reweight the PDF using the current existing MC samples as implemented in CMSSW. First, check out the necessary packages:
scramv1 p CMSSW CMSSW_4_2_3 cvsco -r CMSSW_4_2_3 ElectroWeakAnalysis/Utilities
then replace the LHAPDF library as described here to the current up-to-date one:
or you can directly change in:
with above path:
touch $CMSSW_BASE/src/ElectroWeakAnalysis/Utilities/BuildFile.xml cmsenv scramv1 b cd ElectroWeakAnalysis/Utilities/test
then change the input file in PdfSystematicsAnalyzer.py and run:
cmsRun PdfSystematicsAnalyzer.py
With the up-to-date LHAPDF, one can use CT10, MSTW2008*, CTEQ66, NNPDF2.0, and other PDF sets.
Efficiency estimation uncertainty. The current method for efficiency estimation in the DY analysis is following: we estimate the MC truth efficiency and then we apply the efficiency correction map (Pt-eta) extracted using the data-driven tag and probe method applied to data and MC to weight the MC events. The systematic uncertainty associated with the Tag-and-Probe efficiency estimation is due to line-shape modelling, the difference between fit and counting and due to the binning. The two first are calculated inside the macros described in Step5. The binning systematic uncertainty is estimated using the following macro:
it takes as input the root files having the histogram with efficiency correction as a function of invariant mass with two binnings (to estimate the binning uncertainty), the other sources of uncertainty are also accessed.
The main result of the measurement is the cross-section ratio or r (and R) shape. We distinguish R and r shapes (see the note chapter9 for details on the definition and also see Figures 64). The figure 64 shows the shape R for theory and measurement (for two independent trigger scenarios). It relies on the theoretical cross-section measurement (1-2GeV bin), the final numbers for acceptance correction and also the final numbers for cross-section measurement. To give a clearer feeling of what this plot depends on I name the tables that are used to produce the number in the plot 64:
Table 21-24: Theoretical predictions
Tables 25-26: Measurement
Table 5-10: Acceptance-efficiency corrections
To run the code one simply needs:
cd $CMSSW_RELEASE_BASE/src cvs co UserCode/Purdue/DYAnalysis/AnalysisMacros/GautierMacro cp UserCode/Purdue/DYAnalysis/AnalysisMacros/GautirMacro/* $CONTROL_PLOTS_DIR cd $CONTROL_PLOTS_DIR root -l theory_plot.C++
Use Gautier style macros to get the same plots with different style:
root -l DY.C root -l plot.C
To get all the up to date values for the shape r/R use:
cvs co UserCode/Purdue/DYAnalysis/AnalysisMacros/ShapeR./shapeDY.make ./shapeDY
Among the requirements to style of the results presented is to put the measurement point to the weighted position (i.e. the location of the point inside the bin makes the integral over sub-bins equal from both sides). The following macro can be used to calculate these positions do in root:
.L compare_r.cc; compare_r();
A lot of intersting information can be retrieved from the Zprime JTERM SHORT and LONG exercises (which are constructed along the same lines as this tutorial).

This Is the First Live Recording of Nirvana's Smells Like Teen Spirit
Few bands have so fundamentally affected the American music scene—with a single song, no less—as Nirvana did in 1991 with the debut of Smells Like Teen Spirit. The Beatles did it in 1964 with "Please Please Me" and set off the British Invasion, Grandmaster Flash did it in 1981 with The Message and brought Hip-Hop to the masses.
But when Nirvana's single hit MTV, it not only ushered in the Grunge era, it single-handedly killed off hair metal and forced the music industry in an entirely new direction—MTV exploded with angst-filled tunes practically overnight and the dance hall garbage that had permeated hit charts through the late 1980s fell off faster than their disco predecessors.

Sub Specie Modernitatis. — All that which our forebears thought to note as degeneracy: well, they must have been mistaken, for it led to us.

A Pretty Dichotomy and True. — "Equality is a pretty lie because it pretends to assert commensurability with respect to incommensurable things. When we give up on the idea of equality though it is tempting to replace it with the idea of inequality. This is a mistake. Like its yin equality, the yang inequality carries with it a connotation of commensurability: two things which are unequal are quantitatively comparable along some axis, and one is greater than the other along that axis. So to conclude that (in a comparison of incommensurables) inequality is the case from the fact that equality is false is to make the same mistake that got us here in the first place." 1
With due respect for the author, I must nonetheless disagree. No connotation of commensurability or quantifiability is carried within the concept of inequality per se. Whether or not two things are commensurable, they are unequal by dint of being in fact two things and not one and the same thing. (Incommensurability means we cannot tell of two things which is the better, the greater, etc, not that we do not know that they are unequal in some way.) "Incommensurable" is not a third option between "equal" and "unequal". There is no third option. Either A or not-A, equal or unequal. Hence, giving up on the idea of the equality of things — i.e., regaining humble sanity — just means accepting their inequality, commensurable or not.

Gripes and Bad Faith. — It is anti-democratic to complain about the result of a democratic election. Yet, weirdly, the democratic participant is wont to believe that only he is permitted to complain about it. Lending words to his incoherence, he tells the non-voter, who, unlike him, has not endorsed the election by his participation, that he, the non-voter, must not complain about it. Weird, yes, but not out of keeping with the democrat's ever-present urge to invade the non-democrat's territory and claim it as its own.
He who does not vote in an election has no right to complain about its result.Naturally we dutiful non-voters strongly deny the truth of this and are not wholly disinclined from telling the little blighters who claim it to buzz off and die. But we may also say to them:
To that, we may kindly add: Can I get you another drink? You look as though you need one.I. If you vote in an election, then you must endorse the legitimacy of the process including its result, or else be guilty of bad faith. (You agree in participation of the process to be bound by the rules thereof, which include the acceptance of the legitimacy of the result.)II. You voted in the election.Therefore,III. You must endorse the legitimacy of the result, or else be guilty of bad faith.But (you complain):IV. The result is a disaster.Therefore,V. You must endorse the legitimacy of a disaster about which you complain, or else be guilty of bad faith.
