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.
