Abstract:
    We present a photometric catalog of 2244 objects detected by the
    Ultraviolet Imaging Telescope in the near-ultraviolet (NUV;
    1650A<lambda<2900A) during the Astro-1 Space Shuttle mission. Sources
    in the catalog are as faint as m_nuv∼18.8, or
    f_nuv∼1.1x10-16ergs/s/cm2/A, but the survey is not complete to this
    level. Optical catalogs were used to cross identify sources and derive
    NUV-V colors. A majority of the objects (88%) do indeed have proposed
    optical identifications from catalogs, and most are stars. Our purpose
    in creating the catalog is to form a database useful for identifying
    very blue objects and performing Galactic UV stellar population
    studies.

Note on Type:
  The object is classified with a two-digit number.  The first digit
  represents the UIT filter used for the observation, while the
  second digit represents the type of optical identification.  A
  "0" represents a cataloged stellar identification (either named
  or from the HST GSC), a "1" indicates a nonstellar source, and a
  "2" indicates a proposed match with the digitized POSS (265 sources).
Note on Name:
  Most of the objects (second classification digit "0") match stars
  from the HST GSC, and no name is listed for these objects.
