cds-question@unistra.frultraviolet-photometryvisible-astronomybroad-band-photometryAnalysis of ultraviolet (UV) observations with the FAUST shuttle-borne telescope toward the Antennae and NGC 6752 celestial regions resulted in the detection of 46 and 221 candidate sources respectively, for a signal-to-noise ratio of 8. We discuss the source detection process and the identification of UV sources with optical counterparts. Using correlations with existing catalogues, we present reliable identifications for approximately 60 per cent of the sources. We find that most identified objects are B, A and F stars. The remaining identified objects are galaxies, a white dwarf in a binary system, and two K-type stars. Nearly all of the remaining unidentified objects have assigned optical counterparts but, lacking additional information, we give these only as best estimates. With help from new diagnostic diagrams, we suggest that these unclassified objects are main-sequence (or giant) stars within the local spiral arm or halo; or other hot evolved objects within the local spiral arm. We discuss the nature of the objects found and compare our results with those predicted from spectral and Galactic models.2001MNRAS.324..580Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/324/580CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/252 : The USNO-A2.0 Catalogue (Monet+ 1998)VI/99 : Merged Log of IUE Observations (NASA-ESA, 1999)J/ApJS/96/461 : Far-UV Point Sources (Bowyer+ 1995)J/MNRAS/313/641 : FAUST obs. in the Fourth Galactic Quadrant (Brosch+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/324/580https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/324/580http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/324/580https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/324/580https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/324/580http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/324/580GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/324/580/table1 (Detected UV sources and FAUST sources counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/324/580/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/324/580/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/324/580/table1?GETtext/xml+votable180.050000true181.536-22.86661110.005555555555555556FAUST4/2945 5/11437-11439 11448 11450 11788 11792 11794 6/24820-24821 24823 24825-24826 24828-24829 24831 24971 24992-24994 24996-24998 25002 25006-25008 25010 25016 25019 25169 25172 25174 25344 25346 25350 25352-25353 45747 45798 45805-45807 47117 47119 47141 47143 47156 47158-47160 47164 47172 47174 47180 47182 47200 47202https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/324/580?format=asciiUVOpticaldefaultJ/MNRAS/324/580/table1Detected UV sources and FAUST sources counterpartsrecnoRecord number assigned by the VizieR team.
