Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Abstract:
        Here we report 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 the launch in 2002, up to the end of
        2010. This corresponds to ~110Ms 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 17-100keV energy band, of which
        120 sources represent previously undiscovered soft gamma-ray emitters.
        The source positions are determined, mean fluxes are provided in two
        main energy bands, and these are both reported together with the
        overall source exposure. Indicative levels of variability are
        provided, and outburst times and durations are given for transient
        sources. A comparison is made with previous IBIS catalogs and catalogs
        from other similar missions.

    Note (1):
        N = A new detection since fourth IBIS/ISGRI catalog
             (Bird+, 2010, J/ApJS/186/1).
    Note (2): Expressed as radius of 90% confidence circle.

    Note (3): Expressed in units of mCrab; appropriate conversion factors are:
              (20-40keV) 10mCrab = 7.57e-11erg/cm2/s = 1.71e-3ph/cm2/s;
              (40-100keV) 10mCrab = 9.42e-11erg/cm2/s = 9.67e-4ph/cm2/s.
