INTREFCAT - INTEGRAL Reference Catalog |
HEASARC Archive |
After the launch of INTEGRAL, a version of this catalog was placed on the ISDC website at http://www.isdc.unige.ch/integral/science/catalogue and has been updated periodically since then by adding, for example, new sources discovered by INTEGRAL itself (indicated by the IGR prefix in the name). This HEASARC table is based on the web version at the ISDC, and will be updated within a few days of whenever the latter is updated.
Additional information pertaining to an earlier version of this catalog:
High-energy sources before INTEGRAL. INTEGRAL reference catalog. Ebisawa K., Bourban G., Bodaghee A., Mowlavi N., Courvoisier T.J.-L. <Astron. Astrophys. 411, L59 (2003)> =2003A&A...411L..59E (SIMBAD/NED BibCode)
Source_Number
The INTEGRAL Reference Catalog source number, in order of increasing J2000 RA.
Source_ID
This parameter is the unique identifier for the source, and, will remain the
same even if the source position is modified at a later date.
Name
The INTEGRAL Reference Catalog source name. Often there are two or more names
commonly used for the same source. The authors have taken the name which they
consider to be the most popular in high-energy astrophysics and which is also
used as a SIMBAD source identifier. Thus, users can directly put the source
name into the SIMBAD query box.
RA
The Right Ascension of the high-energy source. In most cases, positions are
taken from SIMBAD. From time to time, however, the authors found and adopted
a more recent position determination than SIMBAD. The accuracy depends on the
individual sources, which was reflected in the representation of the source
positions in the original CDS table where the J2000 RAs were given with a
precision that varied from 0.001 seconds of time to 1 minute of time. To help
users, the HEASARC has added a parameter called ra_precision which has the
following values:
ra_precision meaning 60. position given with 1 minute of time precision 6. position given with 0.1 minutes of time precision 1. position given with 1 second of time precision 0.1 position given with 0.1 seconds of time precision 0.01 position given with 0.01 seconds of time precision 0.001 position given with 0.001 seconds of time precision
Dec
The Declination of the high-energy source. In most cases, positions are taken
from SIMBAD. From time to time, however, the authors found and adopted a more
recent position determination than SIMBAD. The accuracy depends on the
individual sources, which was reflected in the representation of the source
positions in the original CDS table where the J2000 Declinations were given
with a precision that varied from 0.01 arcseconds to 1 degree. To help
users, the HEASARC has added a parameter called dec_precision which has the
following values:
dec_precision meaning 3600. position given with 1 degree of precision 360. position given with 0.1 degrees of precision 60. position given with 1 arcminute of precision 6. position given with 0.1 arcminutes of precision 1. position given with 1 arcsecond of precision 0.1 position given with 0.1 arcseconds of precision 0.01 position given with 0.01 arcseconds of precision
RA_Precision
This parameter encodes the original precision of the RA in
the CDS table on which this HEASARC Browse table is based, as follows:
ra_precision meaning 60. position given with 1 minute of time precision 6. position given with 0.1 minutes of time precision 1. position given with 1 second of time precision 0.1 position given with 0.1 seconds of time precision 0.01 position given with 0.01 seconds of time precision 0.001 position given with 0.001 seconds of time precision
Dec_Precision
This parameter encodes the original precision of the Dec in
the CDS table on which this HEASARC Browse table is based, as follows:
dec_precision meaning 3600. position given with 1 degree of precision 360. position given with 0.1 degrees of precision 60. position given with 1 arcminute of precision 6. position given with 0.1 arcminutes of precision 1. position given with 1 arcsecond of precision 0.1 position given with 0.1 arcseconds of precision 0.01 position given with 0.01 arcseconds of precision
LII
The Galactic Longitude of the high-energy source.
BII
The Galactic Latitude of the high-energy source.
Error_Radius
The positional uncertainty of the high-energy source, in arcseconds.
Pos_Ref
The author(s) of the position reference specified by the pos_ref_bibcode
parameter and possibly other information. In cases of multiple references,
this parameter will contain all of the relevant information.
Pos_Ref_Bibcode
The ADS Bibcode for the source position reference. This is for readers who
need to know the position accuracy and/or position determination method.
Often SIMBAD gives the source position reference as well as the position
itself, in which case the authors have supplied both. Otherwise, they
searched for the proper references themselves.
ISGRI_Flag
This parameter has the value of 0 if the source has not been detected by
ISGRI. It has the value of 1 if the source has been detected by ISGRI. It has
a value of 2 if source has been detected and a position is available with a
precision of less than 3 arcseconds.
ISGRI2_Flag
This parameter has the value of 0 if the source has not been detected by
ISGRI. It has the value of 1 if the source was detected in a single science
window. It has a value of 2 if the source was detected in a mosaic. It has a
value of 5 if the source was a very bright source (used for screening of
background and images).
JEMX_Flag
This parameter has the value of 1 if the source has been detected by JEMX;
otherwise, it is set to 0.
SPI_Flag
This parameter has the value of 1 if the source has been detected by SPI;
otherwise, it is set to 0.
PICSIT_Flag
This parameter has the value of 1 if the source has been detected by PICSIT;
otherwise, it is set to 0.
Source_Type
A characterization of the source type, such as low-mass X-ray binary,
high-mass X-ray binary, Seyfert-1 galaxy, etc.
Alt_Names
Various alternate names for the high-energy source. Since there are
many varieties of sources, the authors did not have a consistent rule to
decide which aliases to choose. However, they did try to put at least one
alias directly related to high-energy satellites and/or catalogs. For example,
"4U" for the 4th Uhuru catalog (Forman et al. 1978, ApJS, 182, 489), and
"2EG" for the 2nd EGRET source catalog (Thompson et al. 1995, ApJS, 101, 259).
Class
The HEASARC Browse object classification, based on the value of the
source_type parameter.
