IRAS Point Source Catalog

The IRAS Point Source Catalog consists of 245,889 sources found and verified by the IRAS (InfraRed Astronomy Satellite). In addition to B1950 positions, flux densities in Janskys (10^-26 W m^-2 Hz^-1) are provided at 12.5, 25, 60, and 100 m^-6 (microns). An L following a flux density indicates that the preceding number is an upper limit; i.e. the source was not detected at that wavelength. Unlike those in the PPM and SAO catalogs, IRAS sources are not uniformly distributed across the sky--IRAS Point Sources tend to be near the galactic equator.

IRAS is a binary version of the IRAS Point Source Catalog ordered by right ascension, as it is distributed. It can be searched by siras (which calls scat) and plotted by skymap.
This 7,376,698-byte file is available via anonymous ftp as ftp://cfa-ftp.harvard.edu/pub/gsc/Catalogs/IRAS.sparc (Sun byte order) and ftp://cfa-ftp.harvard.edu/pub/gsc/Catalogs/IRAS.pc (PC and DEC byte order).

Detailed descriptions of the binary header format and binary entry format are available.
