cds-question@unistra.frradial-velocityob-starsx-ray-sourcesIn this paper the mass of the neutron star in Vela X-1 is determined, by measuring the radial velocity curve of its B supergiant companion. The tables (appendix of the paper), which list the log of observations, and the derived radial velocities, of the blue Coude Echelle Spectrograph (CES) spectra (Table A1), the red CES spectra (Table A2), and the IUE spectra (Table A3).2001A&A...377..925Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/377/925CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/377/925https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/377/925http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/377/925https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/377/925https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/377/925http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/377/925GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-rayOpticaldefaultJ/A+A/377/925/tablea1Observing log and radial velocities for the blue spectra (central wavelength 4102{AA})recnoRecord number assigned by the VizieR team.
