The sky survey performed by the IRAS satellite provides a very homogeneous and almost complete view of the sky at infrared wavelengths. Suitable methods from multivariate statistics and decision theory are employed to extract the extragalactic background included in the IRAS Point Source Catalog. The resulting map comprehensively represents the distribution of extragalactic objects on the sky. The various selections may be used to assess large-scale structure in the distribution of galaxies and the total infrared background due to galaxies, to follow such structures closer to the Galactic Plane than is possible with optical data and to address cosmological questions (e.g., Harmon, Lahav, and Mauers 1987). These investigations are to be extended to the more sensitive Co-Added Catalog.
