Description

The catalog of galaxies and quasars observed by IRAS (the "Extragalactic Catalog") is a compilation of IRAS Point Source Catalog data for objects appearing in the most widely-used extragalactic catalogs. It contains 11,444 IRAS point sources that can be positionally associated with cataloged galaxies and quasars, and gives information on associations of point sources with sources in the IRAS Small Scale Structure Catalog. Because no criteria other than positional coincidence (with a generous search window) were used to match the IRAS sources with their counterparts, the associations should not a priori be accepted as true identifications. Included in the Extragalactic Catalog are the associations of the infrared sources with objects in twelve extragalactic catalogs, among them the UGC, NGC, IC and MCG catalogs, the Arp Atlas, and the Markarian and Zwicky catalogs.
