A catalog of far-ultraviolet point sources detected with the fast FAUST Telescope on ATLAS-1
We list the photometric measurements of point sources made by the FarUltraviolet Space Telescope (FAUST) when it flew on the ATLAS-1 spaceshuttle mission. The list contains 4698 Galactic and extragalacticobjects detected in 22 wide-field images of the sky. At the locationssurveyed, this catalog reaches a limiting magnitude approximately afactor of 10 fainter than the previous UV all-sky survey, TDl. Thecatalog limit is approximately 1 x 10-14 ergs A sq cm/s,although it is not complete to this level. We list for each object theposition, FUV flux, the error in flux, and where possible anidentification from catalogs of nearby stars and galaxies. Thesecatalogs include the Michigan HD (MHD) and HD, SAO, the HIPPARCOS InputCatalog, the Position and Proper Motion Catalog, the TD1 Catalog, theMcCook and Sion Catalog of white dwarfs, and the RC3 Catalog ofGalaxies. We identify 2239 FAUST sources with objects in the stellarcatalogs and 172 with galaxies in the RC3 catalog. We estimate thenumber of sources with incorrect identifications to be less than 2%.

Contact and near-contact binary systems. V - RV Corvi
Reticon spectroscopy and BVRIc photometry are presented for thelate-type eclipsing binary RV Corvi. The system is found to consist ofan unevolved F2 V primary component and a K type secondary componentwhich has a much larger radius and luminosity than expected for itsmass. The binary may be semidetached, with the primary componentcompletely filling its Roche lobe, or may be in a state of marginalcontact. In order to obtain a solution to the photometric data it wasnecessary to treat the secondary component albedo as a free parameter,yielding a value greater than unity. This result implies that there isan abnormal distribution of luminosity on the surface of the binary,which may be interpreted either as an excess of light on the facinghemisphere of one or both of the components, or as a deficit of light onthe averted hemisphere of the secondary.
