Description:
EIC (Equatorial Infrared Catalog) lists positions and other
information for 7,220 infrared stars. Each star is described by a
175-byte print record. The fields within each star record are defined
here. The catalog was prepared as a result of additional processing of
USAF satellite data at 2.7 micrometers for sources within 10 degrees
of the celestial equator. Every source has been observed on two or
more days or on the same day at times 20 minutes apart. The catalog
includes right ascension and declination (equinox B1950.0), flux
densities and their standard deviations, galactic coordinates,
spectral types, and cross identifications to the numbering systems of
EIC-1, the SAO and AFGL catalogs, and the Durchmusterung catalogs.
