INTEGRAL/IBIS 7-year all-sky hard X-ray survey. II. Catalog of sources. Krivonos R., Tsygankov S., Revnivtsev M., Grebenev S., Churazov E., Sunyaev R. <Astron. Astrophys. 523, A61 (2010)> =2010A&A...523A..61K
ADC_Keywords: X-ray sources ; Gamma rays Keywords: surveys - X-rays: general - catalogs Abstract: This paper is the second in a series devoted to the hard X-ray (17-60keV) whole sky survey performed by the INTEGRAL observatory over seven years. Here we present a catalog of detected sources that includes 521 objects, 449 of which exceed a 5σ 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.

Note (1): In some cases, two (or more) lines can contain the same id number in the first column, which are measurements of source flux during the outbursts. Note (2): Spatial confusion, source flux should be taken with the caution. In notes, the spatial confusion with the source XXX is indicated as CXXX. Note (3): Source flux was measured on the 7-year time-averaged map (Dec. 2002 - Jul 2009) or over the indicated spacecraft revolution interval RXXX:XXX. Flux is expressed in units of 10-11erg/s/cm2 Note (4): Source flux was measured on the map averaged over the indicated spacecraft revolution. Note (5): General astrophysical type of the object as follows: LMXB = low-mass X-ray binary HMXB = high-mass X-ray binary AGN = active galactic nucleus SNR/PWN = supernova remnant/pulsar wind nebula CV = cataclysmic variable PSR = isolated pulsar or pulsar wind nebula SGR = soft gamma repeater RS CVn = coronally active binary star SymbStr = symbiotic star Cluster = cluster of galaxies The question mark indicates that the specified type is not firmly determined, so it should be confirmed. Note (6): References are mainly provided for new sources and are related to their discovery and/or nature. Note (7): Redshift of the extragalactic sources was obtained from the SIMBAD and NED database.
