Description:
The Byurakan/Hamburg/ROSAT Catalogue (BHRC) of the optical
identifications of X-ray sources is presented. The BHRC includes all
2791 sources from the ROSAT-FSC (IX/29) with |b|>30, DEC>0 and ROSAT
count rate CR>0.04cts/s. The optical identifications were carried out
by means of the Hamburg Quasar Survey (HQS) digitized spectroscopic
plates, the DSS1 and DSS2 (blue, red, and IR) images, and other
available data. We managed to identify 97% of sources (2696 sources)
that are associated with 3202 optical objects. 2248 X-ray sources have
a single optical counterpart, 144 have a double or multiple optical
counterpart (binaries, galaxy groups etc.), and 304 have ambiguous
identifications. The table gives all available multiwavelength data
for the identified sources.
