Reduced X-ray Count Data

NSSDCA ID: ASXR-00006

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

Time span: 1977-01-06 to 1977-03-08

Description

This data set was obtained by the Scanning Modulation Collimator experiment (HEAO A-3). One file was generated for each of about 1500 trial binning positions at which a possible X-ray source was thought to exist. The files preserve data from each satellite revolution (a 20 s sample at 30 min intervals) and each of the two or three celestial scans (about 4 to 8 days at 6-month intervals) through the region. Raw counts and exposure units are folded and coadded into 60 phase bins for each collimator [30 arc-s and 2 arc-min (FWHM), respectively], for each of three energy channels. This data set is contained on magnetic tape. For additional information on the A-3 data archive, contact Dr. Daniel Schwartz, Smithsonian Astrophysical Observatory, 60 Garden Street, Cambridge, MA 02138.
