Abstract

On April 5, 1991, the Space Shuttle Atlantis carried the Compton gamma ray observatory (CGRO) into orbit, deploying the satellite on April 7. The energetic gamma ray experiment telescope (EGRET) was activated on April 15, and the first month of operations was devoted to verification of the instrument performance. Measurements made during that month and in the subsequent sky survey phase have verified that the instrument time resolution, angular resolution, and gamma ray detection efficiency were all within nominal limits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
