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.
Note (4): Classification as follows:
A = Atoll source (neutron star);
AGN = Active galactic nuclei;
AXP = Anomalous X-ray pulsar;
B = Burster (neutron star);
Be = B-type emission-line star;
BH = Black hole (confirmed mass evaluation);
BHC = Black hole candidate;
BL = broad line;
Cluster = Cluster of galaxies;
CV = Cataclysmic variable;
D = Dipping source;
DN = Dwarf Nova;
G = Globular Cluster X-ray source;
GRB = Gamma-Ray Burst;
HMXB = High-mass X-ray binary;
IP = Intermediate Polar;
LMXB = Low-mass X-ray binary;
M = Microquasar;
Mol Cloud = Molecular cloud;
NL = narrow line;
NS = Neutron Star;
P = Polar;

SG = Supergiant;
SGR = Soft gamma-ray repeater;
SNR = Supernova remnant;
Sy = Seyfert galaxy;
Symb = Symbiotic star;
T = Transient source;
XB = Galactic X-ray binary;
XBONG = X-ray bright, optically normal galaxy;
XP = X-ray pulsar;
Z = Z-type source (neutron star).
Note (5): Variability flag as follows:
Y = bursticity >1.1 (i.e., a 10% increase in significance can be
obtained by selecting a single contiguous subset of the data) and
a slightly variable source.
YY = bursticity of >4 (i.e., a 400% increase in significance),
indicating a strongly variable source.
See Section 3 for details
Note (6): In a single map, see notes on individual sources for detection method.
Note (7):
WARN = the fraction of false sources may be as much as 25%.
See Section 2.4 for details.
Note (8): Around Galactic Center. See Section 2.5 for details.
CGFLAG as follows:
GCFLAG1 = Source lies within the GC box, and is detected by
our standard methods.
GCFLAG2 = Clear evidence of emission from the source position in one or
more of our maps, but it lies within an unresolved emission
region.
