FAUST Catalog
This catalog contains a list of the photometric measurements of
point sources made by the Far Ultraviolet Space Telescope (FAUST) when it
flew on the ATLAS-1 space shuttle mission. The list contains 4660 galactic
and extragalactic objects detected in 22 wide-field images of the sky (note
that the abstract of the published catalog states that it contains 4698
sources: the reason for this discrepancy is not known to the HEASARC). At
the locations surveyed, this catalog reaches a limiting magnitude that is
approximately a factor of 10 fainter than the previous UV all-sky survey,
TD1. The catalog limit is approximately 1x10^-14 ergs/s/cm^2/Angstrom,
although it is not complete to this level. Listed for each object is the
position, Far-UV (FUV) flux, the error in this flux, and, where possible,
an identification from catalogs of nearby stars and galaxies. These catalogs
include the Michigan HD (MHD) and HD Catalogs, the SAO Catalog, the
HIPPARCOS Input Catalog (HIC), the Position and Proper Motion (PPM) Catalog,
the TD1 Catalog, the McCook and Sion Catalog of white dwarf stars, and the
RC3 Catalog of Galaxies. 2239 FAUST sources are identified with objects in
the stellar catalogs and 172 with galaxies in the RC3 catalog. The number of
sources with incorrect identifications is estimated to be less than 2%.
Of the 4660 FUV sources in this catalog, 161 have multiple stellar and/or
galaxy counterparts (155 sources have 2 possible counterparts, 4 sources
have 3 possible counterparts, 1 source has 4 possible counterparts, and 1
source has 6 possible counterparts), with the 4499 remaining FUV sources
having 0 or 1 stellar and/or galaxy counterparts. Hence, there are a grand
total of 4831 = (4499 + 155x2 + 4x3 + 1x4 + 1x6) entries in this database,
since each entry corresponds to a source/counterpart combination.
The HEASARC added a parameter 'multiple_ID' to allow the user to identify
sources with multiple possible counterparts. FAUST Sources with multiple
counterparts thus have multiple entries in this database, and can be
recognized by having multiple_id values greater than 1 (and differing
information in the parameter fields that contain the properties of
the stellar and/or galaxy counterparts).
