cds-question@unistra.frultraviolet-photometryearly-type-starsFar-ultraviolet photometry for 741 objects in a field in Sagittarius centered near M8 and 541 objects in a field centered near zeta Scorpii is presented. These data were extracted from electrographic images obtained with two cameras during a shuttle flight in 1991 April/May. The cameras provided band passes with lambda_eff = 1375 A and lambda_eff = 1781 A. Synthetic colors show that these bands are sensitive to effective temperature for hot stars. Our measurements were placed on a quantitative far-ultraviolet magnitude scale by convolving the spectra of stars observed by IUE with our cameras' spectral response functions. Fifty-eight percent of the ultraviolet objects were identified with visible stars using the SIMBAD database while another 40% of the objects are blends of early type stars too close together to separate with our resolution. Our photometry is compared with that from the TD-1, OAO 2, and ANS satellites and the S201 (Apollo 16) far-ultraviolet camera and found to agree at the level of a few tenths of a magnitude. Unlike previous studies, almost half of the identified visual counterparts to the ultraviolet objects are early B stars. A plot of distance modulus against ultraviolet color excess reveals a significant population of stars with strong ultraviolet excesses.1995ApJS...96..605Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/96/605CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/96/605https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/96/605http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/96/605https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/96/605https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/96/605http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/96/605GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/96/605/table4 (*Ultraviolet objects in the M8 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/96/605/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/96/605/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/96/605/table4?GETtext/xml+votable180.050000true260.4965-24.79780.005555555555555556Cone search capability for table J/ApJS/96/605/table5 (*Ultraviolet objects in the zeta Sco field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/96/605/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/96/605/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/96/605/table5?GETtext/xml+votable180.050000true240.3079-40.42310.0055555555555555564/1798 1804 1805 5/7175 7182 7183 7185 7196 7198 7199 7201 7205 7209 7225 7228 7229 7231 7232 7240 7242 7246 7264 7265 7266 7268 7270 7272 7273 7275 7276 7278 7363 10548 10551 10553 10556 10558 10569 10570 10572 10573 10575 10578 10579 10582 10584 10585 10587 10588 10591 10597 10601 10603 10605 10609 10616 6/28695 28699 28717 28719 28721 28722 28723 28725 28726 28727 28737 28738 28739 28744 28745 28746 28748 28749 28751 28753 28755 28756 28757 28759 28761 28763 28764 28766 28767 28789 28790 28791 28802 28814 28816 28817 28826 28827 28829 28830 28831 28845 28847 28848 28849 28851 28852 28853 28859 28896 28897 28899 28908 28909 28920 28921 28934 28936 28937 28938 28943 28964 28972 28973 28975 28977 28978 28979 28982 28990 29069 29070 29071 29076 29078 29085 29086 29096 29097 29098 29108 29110 29200 29201 29207 29208 29209 29212 29213 29214 29249 29251 29252 29253 29255 29257 29267 29268 29270 29271 29278 29283 29297 29298 29299 29300 29303 29440 29441 29443 29444 29445 29446 29456 29457 29459 29464 29472 42109 42110 42111 42183 42189 42190 42191 42196 42197 42200 42202 42203 42209 42211 42217 42218 42219 42220 42221 42223 42228 42230 42231 42236 42237 42255 42266 42267 42269 42270 42271 42274 42285 42286 42287 42296 42297 42299 42322 42323 42332 42334 42335 42344 42345 42346 42356 42359 42361 42362 42368 42369 42370 42373 42374 42375 42376 42379 42381 42382 42383 42384 42385 42387 42393 42394 42395 42396 42408 42410 42416 42417 42418 42424 42426 42428 42430 42434 42441 42442 42443 42444 42449 42450 42453 42455 42458 42460 42461 42463 42468 42470 42471 42473 42475 42476 42477 42479 42481 42482 42483 42486 42488 42489 42491 42492 42560 42564 42568 42569 42573 42574 42575 42577 42578 42579 42587 42591 42593 42599 42609 42610 42611 42612 42622 42623 42752 42757 42760 42763 42764 42768 42770 42771 42777 42778 42779 42782 42791 42800 42801 42804 42808 42819 42820 42821 42823 42824 42825 42826 42828 42829 42830 42832 42834 42848 42850 47854 47855 47866 47867 47870 48042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/96/605?format=asciiUVdefaultJ/ApJS/96/605/table4*Ultraviolet objects in the M8 fieldSpSpectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
