Scientific paper

This paper is focused on the production of all-sky maps of diffuse gamma radiation in various energy ranges between 30 MeV and 10 GeV. This was carried out using only observational data collected by the EGRET instrument on the Compton Gamma Ray Observatory. This analysis is significantly different from those used in previous work, which considered a combination of data analysis with modeling. Although the maps can be used for a variety of applications, the immediate goal is the generation of diffuse gamma-ray maps which can be used as a starting point for analysis of the data to be obtained from new high-energy gamma-ray missions like GLAST and AGILE. To generate the diffuse gamma maps from the raw EGRET maps, we have first performed a subtraction of the gamma point sources in the Third EGRET Catalog. After that, smoothing was performed to minimize the effects of photon statistical noise. A smoothing length of one degree was used for the region near the Galactic Plane (|b| <=20 degrees). For higher latitudes, a procedure was used which resulted in a smoothing length roughly equivalent to 4 degrees. The result of this work is 15 maps of different energy intervals for regions near the Galactic Plane, and 30 all-sky maps, 15 in equatorial coordinates (J2000) and 15 in galactic coordinates.
