cds-question@unistra.frinterstellar-mediumultraviolet-astronomymilky-way-galaxyTo probe the distribution and physical characteristics of interstellar gas at temperatures T~3x10^5^K in the disk of the Milky Way, we have used the Far Ultraviolet Spectroscopic Explorer (FUSE) to observe absorption lines of OVI{lambda}1032 toward 148 early-type stars situated at distances >1kpc. After subtracting off a mild excess of OVI arising from the Local Bubble, combining our new results with earlier surveys of OVI, and eliminating stars that show conspicuous localized X-ray emission, we find an average OVI midplane density n_0_=1.3x10^-8^cm^-3^. The density decreases away from the plane of the Galaxy in a way that is consistent with an exponential scale height of 3.2kpc at negative latitudes or 4.6kpc at positive latitudes.2008ApJS..176...59Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/176/59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/fuse : The FUSE Observation Log (FUSE, 1999-2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/176/59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/176/59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/176/59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/176/59https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/176/59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/176/59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/176/59/table1 (*Stellar parameters for FUSE target stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/176/59/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/176/59/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/176/59/table1?GETtext/xml+votable180.050000true274.0778806-30.12489580.0055555555555555566/1332 2909 3011 3050 3066 3214 3245 3247 3256 3300 3585 6891 12942 13001 13255 14179 14197 14213 14217 14236 14240 14246 14249 14435 14459 14548 14628 14630 14631 14636 14643 14777 14805 14810 15369 15376 15631 15745 21531 21662 21943 22246 22249 22253 22264 23374 23749 23780 23851 23982 24338 28687 28700 28774 28796 28890 28891 28915 29036 29095 29106 29304 29600 29839 30709 37209 37212 37247 37323 37331 37332 37333 37334 37339 37870 37871 37893 37897 37900 37910 37914 37926 37930 37938 37948 37963 38016 38074 39374 39775 39803 39804 39864 39873 39931 40609 41598 41655 41670 41692 41696 41698 41700 41903 42126 42303 42335 42394 42405 42417 42421 42671 43024 43030 43040 43045 43107 43130https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/176/59?format=asciiUVdefaultJ/ApJS/176/59/table1*Stellar parameters for FUSE target starsrecnoRecord number assigned by the VizieR team.
