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.
