Plot labels and tick marks

Reader René would like to know about some aesthetic issues in plotting:

I have a question regarding labeling. The LTYPE-parameter (eg. in task 'greys') lets you plot "Label in arcsec or other units from reference pixel". This is just what I need, but it stupidly plots it in degrees instead of arcminutes. Is there a way to change this? (Except transforming the coordinates of the whole image I mean ...)

Also is there a way to adjust the number of ticks to plot? (Add minor and major ticks?)

Hi Rene,

Unfortunately, I don't think ltype allows you that kind of control. If you want finer grained control of your labels, you might want to look into plotting with IDL or PGPLOT.
