The stars selected for the atlas were drawn from three populations: Galactic main-sequence (classes III-V) stars, supergiants, and main-sequence stars in the Magellanic Clouds, which have low metallicities. For several of these stars, we have prepared FITS files comprised of pairs of merged spectra for user access via the Multimission Archive at Space Telescope (MAST). We chose spectra from the first population with spectral types O4, O5, O6, O7, O8, and O9.5 and used them to compile tables and figures with identifications of all possible atmospheric and interstellar medium lines in the region 949-1188{AA}. Our identified line totals for these six representative spectra are 821 (500), 992 (663), 1077 (749), 1178 (847), 1359 (1001), and 1798 (1392) lines, respectively, where the numbers in parentheses are the totals of lines formed in the atmospheres, according to spectral synthesis models. The total number of unique atmospheric identifications for the six main-sequence O-star template spectra is 1792, whereas the number of atmospheric lines in common to these spectra is 300. The number of identified lines decreases toward earlier types (increasing effective temperature), while the percentages of "missed" features (unknown lines not predicted from our spectral syntheses) drop from a high of 8% at type B0.2, from our recently published B-star far-UV atlas (Cat. J/ApJS/186/175), to 1%-3% for type O spectra. The percentages of overpredicted lines are similar, despite their being much higher for B-star spectra.2012ApJS..202...17Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/202/17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/129 : The FUSE Observation Log (FUSE, 1999-2007)V/116 : Galactic O star catalog (Maiz-Apellaniz+, 2004)III/115 : IUE Atlas of O-Type Stellar Spectra (Walborn+ 1985)J/ApJS/186/175 : Far-UV spectroscopic atlas of B stars (Smith, 2010)J/ApJS/187/149 : StarCAT: STIS UV echelle spectra of stars (Ayres, 2010)J/ApJ/700/844 : Rotation rates of very massive stars (Penny+, 2009)J/ApJS/144/21 : Galaxy and Magellanic Clouds OB and WR stars (Robert+, 2003)J/ApJS/136/631 : IUE absorption toward 164 early-type stars (Savage+, 2001)J/MNRAS/284/265 : Rotational Velocities of 373 OB stars (Howarth+ 1997)J/ApJS/99/173 : Synthetic UV spectra of massive stars (Leitherer+ 1995)J/A+AS/105/305 : OB stars observed with high dispersion by IUE (Bohlin+ 1994)http://archive.stsci.edu/prepds/fuvostars/ : Supplementary materials for thehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/202/17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/202/17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/202/17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/202/17https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/202/17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/202/17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/202/17/table1 (Star list for O star far-UV spectral atlas)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/202/17/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/202/17/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/202/17/table1?GETtext/xml+votable180.050000true84.06095-67.65532780.0055555555555555566/15745 22249 23982 33095 33106 33112 33306 33317 33328 37333 37930 38016 39775 42417 43030https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/202/17?format=asciiUVdefaultJ/ApJS/202/17/table1Star list for O star far-UV spectral atlasSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
