IRAS Point Source Catalog, Version 2.0

Listed in NASA Data Portal

Description

The IRAS Point Source Catalog, Version 2.0, is a catalog of some 250,000 well-confirmed infrared point sources observed by the Infrared Astronomical Satellite (IRAS), i.e., sources with angular extents less than approximately 0.5, 0.5, 1.0, and 2.0 arcminutes in the in-scan direction at 12, 25, 60, and 100 microns (µm), respectively. Positions, flux densities, uncertainties, associations with known astronomical objects and various cautionary flags are given for each objectin the catalog.

Away from confused regions of the sky, the survey is complete to about 0.4, 0.5, 0.6, and 1.0 Janskies (Jy) at 12, 25, 60, and 100 microns, respectively. Typical position uncertainties are about 2 to 6 arcseconds in the in-scan direction and about 8 to 16 arcseconds in the cross-scan direction. This online version of the IRASPSC was created by the HEASARC in April 2002 based on ADC/<a href="cdsarc.cds.unistra.fr/ftp/cats/II/125">CDS Catalog II/125</a> (the main file).
