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 (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.
