HEAO 1 A2 Spectra
Listed in NASA Data Portal
The A2 experiment was flown on the HEAO-1 satellite, between August, 1977 until January 1979.
Description
The experiment consisted of six multi-layer multi-anode collimated gas proportional counters. These were two LEDs (Low Energy Detectors), a MED (Medium Energy Detector), and three HEDs (High Energy Detectors).
The first 6-months of mission were dedicated to an all-sky scan after which a pointing phase started. This database accesses the spectra (and associated files) obtained from the A2 MED (small and large field of view) and HEDs (1 and 3 small and large filed of view) detectors during the pointed phase. The spectra were generated for all HEAO-1 A2 pointed observations except for those in more unusual HEAO-1 modes (RAM-11 and "radical RAMs").

Thus the set of spectra created are only a subset (though a fairly complete one) of the entire catalog of HEAO-1 A2 pointed observations. This is a service provided by NASA HEASARC .
