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:
        This paper is the second in a series devoted to the hard X-ray
        (17-60keV) whole sky survey performed by the INTEGRAL observatory over
        seven years. Here we present a catalog of detected sources that
        includes 521 objects, 449 of which exceed a 5{sigma} detection
        threshold on the time-averaged map of the sky, and 53 were detected in
        various subsamples of exposures. Among the identified sources with
        known and suspected nature, 262 are Galactic (101 low-mass X-ray
        binaries, 94 high-mass X-ray binaries, 37 cataclysmic variables, and
        30 of other types) and 221 are extragalactic, including 217 active
        galactic nuclei (AGNs) and 4 galaxy clusters. The extragalactic
        (|b|>5deg) and Galactic (|b|<5deg) persistently detected source
        samples have high identification completeness (respectively ~96% and
        ~93%) and are valuable for population studies.

         so it differs from the table available in the published paper.

    Note (1): In some cases, two (or more) lines can contain the same id number
         in the first column, which are measurements of source flux during the
         outbursts.
    Note (2): Spatial confusion, source flux should be taken with the caution.
         In notes, the spatial confusion with the source XXX is indicated as CXXX.
    Note (3): Source flux was measured on the 7-year time-averaged map (Dec.
         2002 - Jul 2009) or over the indicated spacecraft revolution interval
         RXXX:XXX. Flux is expressed in units of 10-11erg/s/cm2
    Note (4): Source flux was measured on the map averaged over the indicated
         spacecraft revolution.
    Note (5): General astrophysical type of the object as follows:
      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
      RS CVn  = coronally active binary star
      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 (6): References are mainly provided for new sources and are related to
         their discovery and/or nature.
    Note (7): Redshift of the extragalactic sources was obtained from the
         SIMBAD and NED database.
