Source Target List Sorted by Time and Right Ascension Data

NSSDCA ID: ASXR-00035

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1977-11-15 to 1978-12-29

Description

This data set contains lists of targets that the HEAO A-2 experiment pointed at during its mission. The lists are identical except that one is ordered by time and the other is ordered by right ascension of the Y axis. Each list has ten columns of information: target name, whether the target was on the +Y or -Y side of the spacecraft, RA and Dec of Y axis (1950 epoch), day and second of 1977 of start of pointing, day and second of 1977 of end of pointing, 'PP' indicating spacecraft alternated between two positions during pointing, and pointing number. This data set consists of EBCDIC magnetic tape, created on the IBM 3081, with three binary header records. For further detailed information on the A-2 data archive, contact Dr. Elihu Boldt, Code 661, GSFC/NASA, Greenbelt Road, Greenbelt, MD 20771.
