cds-question@unistra.fropen-star-clustersb-starsradial-velocityWe derive single-epoch radial velocities for a sample of 56 B-type stars members of the subgroups Upper Scorpius, Upper Centaurus Lupus and Lower Centaurus Crux of the nearby Sco-Cen OB association. The radial velocity measurements were obtained by means of high-resolution echelle spectra via analysis of individual lines. The internal accuracy obtained in the measurements is estimated to be typically 2-3km/s, but depends on the projected rotational velocity of the target. Radial velocity measurements taken for 2-3 epochs for the targets HD120307, HD142990 and HD139365 are variable and confirm that the y are spectroscopic binaries, as previously identified in the literature. Spectral lines from two stellar components are resolved in the observed spectra of target stars HD133242, HD133955 and HD143018, identifying them as spectroscopic binaries.2006A&A...448.1001Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/448/1001CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/213 : General Catalog of radial velocities (Barbier-Brossat+, 2000)J/A+A/356/541 : T Tauri stars in the Sco-Cen OB association (Koehler+, 2000)J/ApJS/82/117 : UBV and H-beta in Sco-Cen association (Slawson+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/448/1001https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/448/1001http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/448/1001https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/448/1001https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/448/1001http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/448/1001GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/448/1001/table1 (Radial velocities of observed Sco-Cen OB stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/448/1001/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/448/1001/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/448/1001/table1?GETtext/xml+votable180.050000true170.2516944-54.49101920.0055555555555555566/30722 37888 37990 41516 41534 41606-41607 41705 41917 41947 41963 41973 41982-41983 42428 42633 42656 42728 42738 42924 42948 42977 42994 43011 43018 43035 43056 43062 43067 43099 43137 43183 43211 43238 43307 43338 43345 43397 43414 43416 43429 43521 43531 43538 44086 44119 44305 44310 44366 44385 44389https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/448/1001?format=asciiOpticaldefaultJ/A+A/448/1001/table1Radial velocities of observed Sco-Cen OB starsGroupGroup (1)meta.idcharHDHD numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
