IBISCAT ivo://nasa.heasarc/ibiscat NASA/GSFC HEASARC Bird et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This table contains an all-sky soft gamma-ray source catalog based on IBIS observations performed during the first 1000 orbits of INTEGRAL. The database for the construction of the source list consists of all good-quality data available, from the launch of INTEGRAL in 2002, up to the end of 2010. This corresponds to ~ 110 Ms of scientific public observations, with a concentrated coverage on the Galactic Plane and extragalactic deep exposures. This new catalog includes 939 sources above a 4.5-sigma significance threshold detected in the 17-100 keV energy band, of which 120 sources represent previously undiscovered soft gamma-ray emitters. The source positions are determined, mean fluxes are provided in two main energy bands, and these are both reported together with the overall source exposure. Indicative levels of variability are provided, and outburst times and durations are given for transient sources. In the reference paper, a comparison is made with previous IBIS catalogs and catalogs from other similar missions. This database table, the Fifth IBIS/ISGRI source catalog, was ingested by the HEASARC in September 2016 based on the machine-readable version of Table 2 of the above-cited paper, which was obtained from the CDS website. It replaced the previous (fourth) version.
