HEAO 1 A2 Scanned Lightcurves
Listed in NASA Data Portal
The A2 experiment was flown on the HEAO-1 satellite, from 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 table accesses the lightcurves available at HEASARC obtained from the A2 MED (small and large field of view) and HEDs (3 units, each with small and large field of view) detectors during the scanning phase. This is a service provided by NASA HEASARC .
