A-2 South Ecliptic Pole (SEP) Database

NSSDCA ID: ASXR-00053

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

Time span: 1977-08-12 to 1979-01-09

Description

The HEAO-1 A-2 SEP database is one of the secondary data bases derived from the MAX primary data base (77-075A-2N). MAX database records for observations of the South Ecliptic Pole region (cone of 12 degrees centered on the Large Magellanic Cloud) are extracted and reformatted. No analysis has been performed except to include quality flags for clean, superclean, source-in-field-of-view, pointing mode and digital status in the output record. A data analysis package is available on the microVAX of the GSFC Laboratory for High Energy Astrophysics.
