IRAS Serendipitous Survey Catalog

The SSC is a catalog of 12, 25, 60 and 100 micron photometric observations of 43,866 point-like sources detected fortuitously in the IRAS Pointed Observation program. The main objective was to take advantage of the longer-than-normal integration time per source to extend the detection threshold relative to that of the Point Source Catalog (PSC); about three-fourths of the SSC sources do not appear in the PSC. From 1813 Pointed Observation (PO) fields, the effective sky coverage is 1108 sq deg. 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, and much greater depth in crowded fields at the expense of reliability and accuracy.
