obs_description      = This data presents all-sky maps of diffuse gamma radiation in energy ranges between 100 MeV to 150 MeV, based on data collected by the EGRET instrument on the Compton Gamma Ray Observatory. EGRET detected gamma rays in the energy range from 30 MeV to over 30 GeV, with an energy resolution of 20-25% over most of that range. The instrument is described in Hughes et al. (1980), Kanbach (1988, 1989), Thompson et. al (1993) and Esposito et al. (1998). The work described here started with standard EGRET all-sky maps (ftp://cossc.gsfc.nasa.gov/compton/data/egret/high_level/combined_data) of photon counts, instrument exposure, and gamma-ray intensity, binned in 0.5 degree pixels, in both Galactic and equatorial coordinates. The energy ranges in MeV are: (narrow ranges) 30-50, 50-70, 70-100, 100-150, 150-300, 300-500, 500-1000, 1000-2000, 2000-4000, 4000-10000; (broader ranges) 30-100, 100-300, 300-1000; (integral ranges) >100, >300, >1000.
