Abstract:
In this paper we report on the third soft gamma-ray source catalog
obtained with the IBIS/ISGRI gamma-ray imager on board the INTEGRAL
satellite. The scientific data set is based on more than 40Ms of
high-quality observations performed during the first 3.5yr of Core
Program and public IBIS/ISGRI observations. Compared to previous
IBIS/ISGRI surveys, this catalog includes a substantially increased
coverage of extragalactic fields, and comprises more than 400
high-energy sources detected in the energy range 17-100keV, including
both transients and faint persistent objects that can only be revealed
with longer exposure times.
Description:
The data are collected with the low-energy array, ISGRI (INTEGRAL Soft
Gamma-Ray Imager), consisting of a pixellated 128x128 CdTe solid-state
detector that views the sky through a coded aperture mask. IBIS/ISGRI
generates images of the sky with a 12' (FWHM) resolution and arcmin
source location accuracy over a 19°(FWHM) field of view in the
energy range 15-1000keV.
This "all-sky" catalog uses mosaic image data from the first 3.5yr of
IBIS/ISGRI Core Program and public observations. The data set used in
this catalog ensures that >70% of the sky is now observed with an
exposure of at least 10ks. As with previous catalogs, the aim is to
provide a prompt release of information to the community.
