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.

Note on table2.dat: This is the corrected version of table2 (from author),
     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.
