HEAO 1 A2 Pointing Catalog
The HEAO 1 A-2 Pointing Catalog of High-Energy X-ray Sources is the result of a study of selected targets using the three detectors of the A-2 Experiment. The detectors consisted of the HED (high energy detector) in the range 3-6 KeV, the MED (medium energy detector) in the range 1.5-15 KeV, and the LED (low energy detector) in the range 0.15-3 KeV. The HEAO A-2 Experiment was primarily designed for studying the diffuse X-ray background; however, it was also capable of studying point sources to good sensitivity. Thus, after several months of continuous scanning to survey 95% of the diffuse X-ray sky, the A-2 detectors began individual pointings at selected targets. The point maneuvers began on day 319, 15 November 1977 and ended on day 739, 9 January 1979. This is a service provided by NASA HEASARC .
