INTEGRAL Bright Source Catalog

The INTEGRAL Bright Source Catalog is based on publicly available data from the two main instruments (IBIS and SPI) on board INTEGRAL (see Winkler et al. 2003, A&A, 411, L1 for a description of the INTEGRAL spacecraft and instrument packages). INTEGRAL began collecting data in October 2002. This catalog will be regularly updated as data become public (~14 months after they are obtained). The Bright Source Catalog is a collaborative effort between the INTEGRAL Science Data Center (ISDC) in Switzerland and the NASA Goddard Space Flight Center (GSFC) INTEGRAL Guest Observer Facility (GOF). The results presented here are a result of a semi-automated analysis and they should be considered as approximate: they are intended to serve as a guideline to those interested in pursuing more detailed follow-up analyses. The data from the imager ISGRI (Lebrun et al. 2003, A&A, 411, L141) have been analyzed at the INTEGRAL Science Data Centre (ISDC), while the SPI (Vedrenne et al. 2003, A&A, 411, L63) data analysis was performed at GSFC as a service of the INTEGRAL GOF. This database table was first created in September 2004. It is based on the online web page maintained by the INTEGRAL GOF at the URL <a href="http://heasarc.gsfc.nasa.gov/docs/integral/INTEGRAL_bright_sources.html">http://heasarc.gsfc.nasa.gov/docs/integral/INTEGRAL_bright_sources.html</a> and is updated on a weekly basis whenever the web page is updated. This is a service provided by NASA HEASARC.
