Application of SFD Dust Maps to Galaxy Counts and CMB Experiments
  We have constructed a full-sky map of the far-infrared suitable for measuring Galactic reddening and extinction (Schlegel, Finkbeiner & Davis 1998: SFD). The SFD map is based upon extensive re-analysis of data from the COBE/DIRBE and IRAS satellite missions. We demonstrate that the maps can correct for extinction problems in the APM galaxy survey. We also determine the most dust-free regions for conducting cosmic microwave background or soft X-ray experiments of extragalactic objects.
