Description:
The catalog is a compilation of X-ray sources containing 677 objects
known as of 1979 September. X-ray data for 677 sources are the result
of X-ray sky surveys by rockets, balloons, and satellites during
1964-1979. The sky survey is practically complete to X-ray intensities
of nearly 4 micro-Jy in the 2-6 keV range. The current version does
not include the investigation by HEAO 2. The catalog includes source
names, positions of the maximum probability densities, date of the
measurements, the type of measuring systems, the ranges at which the
measurement was performed, maximum intensities for constant sources,
and ratio of the maximum observed value of intensity to the minimum
one for variable sources.
The catalog is an update of the publication, by the same authors, in
1979ApJS...41..327A 1979ApJS...41..327A

History:
The catalog was originally designated VII/81 (December 1986); some
inconsistencies were corrected by Wayne H. Warren Jr (ADC) in December
1986, and the Description was added by Gail L. Schneider [SSDOO/ADC]
* 30-Dec-2003: catalog was reformatted at CDS (Francois Ochsenbein)
to accommodate single format records.
