Description:
The UV observations of FAUST are analysed in four sky fields (Dor,
Cen, M81 and Tel), located in the general direction of the Fourth
Galactic Quadrant, where 777 UV sources are detected, about 50% more
than detected originally by Bowyer et al. (1993ApJ...415..875B 1993ApJ...415..875B).
Ground-based objective-prism information for two of the fields were
used to select the best-matching optical objects with which to
identify the UV sources. Using this, and correlations with existing
catalogues, reliable identifications are presented for about 75% of
the sources. Most of the remaining sources have assigned optical
counterparts but, lacking additional information, we offer only
plausible identifications.
FAUST is a wide-field telescope (7.6° diameter) designed to image
diffuse and point sources in the wavelength range 140-180nm. The
experiment, the mission and the data are described in a previous paper
by Bowyer et al., 1993ApJ...415..875B 1993ApJ...415..875B .

--------------------------------------------------------------------------------
Note (1): The formal positional accuracy of the detected UV sources is
∼10arcsec, but the large point spread function of FAUST implies that
the positions may have larger errors than the formal fit. For this
reason, we list the UV sources with positions to the nearest second.
