The IBIS soft gamma-ray sky after 1000 INTEGRAL orbits

Understand

We report here an all-sky soft gamma-ray source catalog based on IBIS observations performed during the first 1000 orbits of INTEGRAL.

• The database for the construction of the source list consists of all good quality data available from launch in 2002 up to the end of 2010.
• This corresponds to $\sim$110 Ms of scientific public observations with a concentrated coverage on the Galactic Plane and extragalactic deep exposures.
• This new catalog includes 939 sources above a 4.5 sigma significance threshold detected in the 17-100 keV energy band, of which 120 represent previously undiscovered soft gamma-ray emitters.
