J/A+A/545/A27  INTEGRAL/IBIS 9-year Galactic Hard X-Ray Survey (Krivonos+, 2012)

INTEGRAL/IBIS nine-year Galactic hard X-Ray survey. Krivonos R., Tsygankov S., Lutovinov S., Revnivtsev M., Churazov E., Sunyaev R. <Astron. Astrophys. 545, A27 (2012)> =2012A&A...545A..27K
ADC_Keywords: X-ray sources ; Gamma rays ; Surveys Mission_Name: INTEGRAL Keywords: surveys - X-rays: general - catalogs Abstract: We present sky images, sensitivity maps, and catalogs of detected sources in the three energy bands 17-60, 17-35, and 35-80keV in the Galactic plane at |b|<17.5 degrees. The total number of sources in the reference 17-60keV band includes 402 objects exceeding a 4.7σ detection threshold on the nine-year time-averaged map. Among the identified sources with known and tentatively identified natures, 253 are Galactic objects (108 low-mass X-ray binaries, 82 high-mass X-ray binaries, 36 cataclysmic variables, and 27 are of other types), and 115 are extragalactic objects, including 112 active galactic nuclei (AGNs) and 3 galaxy clusters. The sample of Galactic sources with S/N>4.7 sigma has an identification completeness of ∼92%, which is valuable for population studies. Since the survey is based on the nine-year sky maps, it is optimized for persistent sources and may be biased against finding transients. File Summary:

Every directory contains six directories with corresponding 70x36 deg. sky mosaics: GAL-Survey+115 (l=+115°), GAL-Survey+50 (l=+50°), GAL-Survey-115 (l=-115°), GAL-Survey-50 (l=-50°), GAL-Survey-AC (l=180°) and GAL-Survey-GC (l=0°). Files are : *.fpsf.fits - sky flux in mCrab, convolved with instrumental PSF (2D Gaussian, σ=5') *.epsf.fits - 1 σ errors, mCrab (PSF convolved) *.spsf.fits - significance map, (PSF convolved) *_mapdld.fits - raw sky mosaics (not convolved with PSF) *.png - images in PNG format Byte-by-byte Description of file: catalog.dat

Note (1): Spatial confusion, source flux should be taken with the caution. In notes, the spatial confusion with the source XXX is indicated as CXXX. Note (2): Source flux was measured on the nine-year time-averaged map (Dec 2002 - Jan 2011). Flux is expressed in mCrab units. Note (3): General astrophysical type of the object: 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 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 (4): References are mainly provided for new sources and are related to their discovery and/or nature. Note (5): The spatial confusion with the source XXX is indicated as CXXX. The measured flux of sources being in spatial confusion should be taken with the caution. Redshift of the extragalactic sources was obtained from the SIMBAD and NED database.
