These sources are, or have been at least once, brighter than ~1 milliCrab above 3 keV energy, and are expected to be detected by INTEGRAL. This catalog was used in the INTEGRAL Quick Look Analysis (QLA) to discover new sources or significantly variable sources. The authors compiled several published X-ray and gamma-ray catalogs, and surveyed recent publications for new sources. Consequently, there were 1121 sources in the original INTEGRAL Reference Catalog. In addition to the source positions, an approximate spectral model and expected flux were given for each source, and the expected INTEGRAL counting rates based on these parameters was derived. Assuming the default instrument performances and at least ~10<sup>5</sup> seconds exposure time for any part of the sky, it is expected that INTEGRAL will detect at least ~700 sources below 10 keV and ~400 sources above 20 keV over the mission life. After the launch of INTEGRAL, a version of this catalog was placed on the ISDC website at <a href="http://www.isdc.unige.ch/integral/science/catalogue">http://www.isdc.unige.ch/integral/science/catalogue</a> 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. This database table is updated automatically in the HEASARC database system within one week of any changes to the online web page maintained by the INTEGRAL Science Data Center at the URL <a href="http://www.isdc.unige.ch/integral/catalog/latest/catalog.html">http://www.isdc.unige.ch/integral/catalog/latest/catalog.html</a> This is a service provided by NASA HEASARC . 2003A&A...411L..59E https://heasarc.gsfc.nasa.gov/W3Browse/all/intrefcat.html Catalog Research served-by HEASARC TAP https://heasarc.gsfc.nasa.gov/xamin/vo/cone?showoffsets&table=intrefcat& GET text/xml 180 99999 true 78.5 -88.2 0.25 https://heasarc.gsfc.nasa.gov/xamin/vo/tap https://heasarc.gsfc.nasa.gov/cgi-bin/W3Browse/getvotable.pl?name=intrefcat GET text/xml https://heasarc.gsfc.nasa.gov/cgi-bin/W3Browse/w3query.pl?tablehead=name=heasarc_intrefcat&Action=More+Options&Action=Parameter+Search&ConeAdd=1 INTEGRAL 0.25 Gamma-ray X-ray public intrefcat INTEGRAL Reference Catalog source_id Unique Source Identifier meta.id char nullable name Source Designation meta.id;meta.main char nullable ra Right Ascension degree pos.eq.ra;meta.main double nullable dec Declination degree pos.eq.dec;meta.main double nullable error_radius Positional Uncertainty (arcseconds) arcsec stat.error;pos double nullable pos_ref Position Reference, Author Name and Possibly Other Info meta.bib.author char nullable pos_ref_bibcode Position Reference, Bibcode meta.bib.bibcode char nullable source_type Source Type src.class char nullable source_number Sequential Identification Number for Each Source in Catalog meta.id short nullable spi_flag Flag Indicates Source Detected by SPI meta.code;obs short nullable dec_precision Declination Precision (arcseconds) arcsec stat.error;pos.eq.dec double nullable isgri2_flag Flag Indicates Information About How the Source Was Detected by ISGRI meta.code;obs short nullable alt_names Source Name Alias(es) meta.id char nullable isgri_flag Flag Indicates Source Detected by ISGRI meta.code;obs short nullable lii Galactic Longitude degree pos.galactic.lon double nullable jemx_flag Flag Indicates Source Detected by JEMX meta.code;obs short nullable class Browse Object Classification src.class short nullable bii Galactic Latitude degree pos.galactic.lat double nullable picsit_flag Flag Indicates Source Detected by PICSIT meta.code;obs short nullable ra_precision Right Ascension Precision (seconds) s stat.error;pos.eq.ra double nullable "__x_ra_dec" System unit vector column double nullable "__y_ra_dec" System unit vector column double nullable "__z_ra_dec" System unit vector column double nullable "__row" System index column char nullable
