Abstract

Aims. We present a catalog of point γ-ray sources detected by the EGRET detector on the Compton Gamma Ray Observatory. We used the entire γ-ray dataset of reprocessed photons at energies above 100 MeV and new Galactic interstellar emission models based on CO, HI, dark gas, and interstellar radiation field data. Two different assumptions are used to describe the cosmic-ray distribution in the Galaxy to analyse the systematic uncertainties in source detection and characterization.
