Description
The INTEGRAL IBIS All-Sky Survey of Hard X-Ray Sources table contains the results from a paper which is the second in a series devoted to the hard X-ray (17 - 60 keV) whole sky survey which has been performed by the INTEGRAL observatory over its first seven years of observations. This table contains the catalog of detected sources and includes 521 objects, 449 of which exceed a 5-sigma detection threshold on the time-averaged map of the sky, and 53 which were detected in various sub-samples of exposures. Among the identified sources with known and suspected natures, 262 are Galactic (101 low-mass X-ray binaries, 94 high-mass X-ray binaries, 37 cataclysmic variables, and 30 of other types) and 221 are extragalactic, including 217 active galactic nuclei (AGNs) and 4 galaxy clusters. The extragalactic (|b| > 5 degrees) and Galactic (|b| < 5 degrees) persistently detected source samples have high identification completeness (respectively ~96% and ~93%) and are valuable for population studies. The current INTIBISASS table is based on the data provided in Krivonos et al. (2010: Paper II below) and replaces the earlier version available at the HEASARC from February 2008 to December 2010 which was based on Krivonos et al. (2007). This table was updated by the HEASARC in December 2010 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/523/A61">CDS catalog J/A+A/523/A61</a> (specifically, the table2.dat and refs.dat files). It was originally created by the HEASARC in February 2008 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/475/775">CDS catalog J/A+A/475/775</a>, which was superseded by this version. This is a service provided by NASA HEASARC .
