Description
The detection efficiency of EGRET varied throughout the mission due to aging of the spark gas between gas refills, and later in the mission due to partial hardware failures. After the gas refill in 1995 September until the end of the mission in 2000 May, EGRET was operated for approximately 700 days--several times as long as for earlier gas fills. The efficiency degradation was severe during this time, and it was highly energy dependent affecting the low energies the most. This paper reports on an extensive effort to determine the efficiency factors that apply to data during this period
