Abstract:
The Infrared Astronomical Satellite (IRAS) Serendipitous Survey Catalog (SSC) was constructed from pointed observations made by the satellite when it was in Additional Observations (AO), i.e., non-survey, mode. Analysis of the SSC shows that it contains a higher percentage of sources which have been detected only at 60mum than are found in the IRAS Point Source Catalog (PSC). This could reflect the existence of a large population of faint extragalactic (galaxian) objects due to the increased sensitivity of the SSC relative to the PSC, especially in the 60 mum band, or simply be a result of spurious sources in the SSC. Inspection of cirrus contamination over each AO showed that it had little or no effect on the high 60 mum-only source count. An automated optical identification program presented here indicated that 60 mum-only sources were as likely to have optical counterparts as all other sources, and more likely than randomly-placed artificial sources. The SSC sources studied had, on average, one more optical source found nearby than did artificial data: probably the optical counterpart to the IRAS source. These results support the validity of the 60 mum-only sources and the SSC in general.
