Query: FAUST Observations in the Fourth Galactic Quadrant   We analyze 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 (1995). 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 catalogs, we present reliable identifications for
\~75% of the sources. Most of the remaining sources have assigned optical
counterparts, but lacking additional information we offer only plausible
identification. We discuss the types of objects found, and compare the observed
population with predictions of our UV Galaxy model.
