The UK ASCA Data Archive
The Advanced Satellite for
Cosmology and Astrophysics (ASCA) is Japan's fourth cosmic X-ray astronomy mission
and has been in operation since February 1993. ASCA is the first X-ray astronomy
mission to combine imaging capability with a broad pass band, good spectral resolution,
and a large effective area. The mission is also the first satellite to use CCDs
for X-ray astronomy.
The ASCA archive contains all data which has been released
to the public domain from observations in the PV and guest observer phases of
the mission. The UK archive is based upon the ASCA Public Data Archive held at
the High Energy Astrophysics Science Archive Research Center (HEASARC)
and was provided by the HEASARC as a set of 150 CD-ROMs (= appx 98 Gb). Users
of the ASCA Archive in the UK (and Europe) are recommended to use this version
to take advantage of faster data transfer rates.
