Sources in the catalog are as faint as m_nuv ~ 18.8, or f_nuv ~ 1.1 x 10^-16 ergs/s/cm^2/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.

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). Name: Most of the objects (second classification digit "0") match stars from the HST GSC, and no name is listed for these objects. -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 16-Jul-96
