IRAS Serendipitous Survey Catalog

The Infrared Astronomical Satellite (IRAS) Serendipitous Survey Catalog (SSC) is a catalog of 12, 25, 60 and 100 micron photometric observations of 43,866 point-like sources detected fortuitiously in the IRAS Pointed Observation program. The main objective was to take advantage of the longer-than-nominal integration time per source to extend the detection threshold relative to that of the IRAS Point Source Catalog (PSC); about three-fourths of the SSC sources do not appear in the PSC. From 1813 Pointed Observation fields, the effective sky coverage is 1108 square degrees. Relative to the PSC, the SSC is characterized by: enhanced sensitivity (by a factor of about 4) in all four wavelength bands; excellent reliability in uncrowded fields; uneven sky coverage and completeness; reduced positional accuracy; improved photometric accuracy; much greater depth in crowded fields at the expense of reliability and accuracy. More information about the SSC data processing, the catalog format, and an analysis are given in the Explanatory Supplement to the IRAS Serendipitous Survey Catalog. This Browse table was created by the HEASARC in December 2006 based on CDS table II/126, the file sources.dat. More information, e.g., on counterparts in other catalogs to the SSC sources, is available in other files in the directory <a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/126/">https://cdsarc.cds.unistra.fr/ftp/cats/II/126/</a> This is a service provided by NASA HEASARC .
