Abstract
We describe the INTEGRAL reference catalog which classifies previously known
bright X-ray and gamma-ray sources before the launch of INTEGRAL.
These sources are, or have been at least once, brighter than ~
1 mCrab above 3 keV,
and are expected to be detected by INTEGRAL.
This catalog is being used in the INTEGRAL Quick Look Analysis to discover new sources or
significantly variable sources.
We compiled several published X-ray and gamma-ray catalogs, and surveyed recent
publications for new sources.
Consequently, there are 1122 sources in our INTEGRAL reference catalog. In addition
to the source positions, we show an approximate spectral model and expected flux for each source, based on
which we derive expected INTEGRAL counting rates. Assuming the
default instrument performances and
at least ~
105 s exposure
time for any part of the sky, we expect that INTEGRAL will detect
at least ~700 sources below 10 keV and ~400 sources above 20 keV over the mission life.
Key words: INTEGRAL -- X-ray sources -- gamma-ray sources -- catalog
