INTEGRAL all-sky survey of hard X-ray sources

Here we present a catalog of detected sources that includes 521 objects, 449 of which exceed a 5{sigma} detection threshold on the time-averaged map of the sky, and 53 were detected in various subsamples of exposures. Among the identified sources with known and suspected nature, 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|>5deg) and Galactic (|b|<5deg) persistently detected source samples have high identification completeness (respectively ~96% and ~93%) and are valuable for population studies.
