J/ApJ/607/L33 First IBIS Catalog: 20-100keV (Bird+, 2004) ================================================================================ The first IBIS/ISGRI Soft Gamma-Ray Galactic Plane Survey Catalog.

The analysis has been performed on the first-year Core Program ISGRI data comprising both Galactic Plane Scan and Galactic Centre Deep Exposure pointings for a total exposure time exceeding 5Ms. This initial survey has revealed the presence of ~120 sources detected with the unprecedented sensitivity of ~1mCrab in the energy range 20-100keV. Each source is located to an accuracy between 1' and 3', depending on its brightness. The outstanding IBIS capability to locate soft {gamma}-ray emitters has allowed us to identify most of the detected sources with already known Galactic X-ray binary systems, while 28 of the objects are of unknown nature. Description: The data set consists of all Core Program observations (the Galactic Plane Scan and the Galactic Centre Deep Exposure) performed between 2003 February 28 (revolution 46) and October 10 (revolution 120), a total of 2529 pointings.
