Abstract:
We analyse UV observations with FAUST of four sky fields in the
general direction of the Fourth Galactic Quadrant, in which we
detect 777 UV sources. This is ~50% more than detected originally by
Bowyer et al. (1993ApJ...415..875B). We discuss the source detection
process and the identification of UV sources with optical
counterparts. For the first time in this project we use ground-based
objective-prism information for two of the fields, to select the
best-matching optical objects with which to identify the UV sources.
Using this, and correlations with existing catalogues, we present
reliable identifications for ~75 per cent of the sources. Most of the
remaining sources have assigned optical counterparts but, lacking
additional information, we offer only plausible identifications. We
discuss the types of objects found, and compare the observed
population with predictions of our UV Galaxy model.

--------------------------------------------------------------------------------
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.
