cds-question@unistra.fropen-star-clustersspectroscopic-binary-starsradial-velocityWe report on a comprehensive, long-term monitoring programme aiming to improve our knowledge of such binary systems. We monitored the radial velocities of 1309 red giants in 187 open clusters with the Coravel spectrometers for 20 years, with a typical accuracy of 0.4km/s per observation. In total, 289 spectroscopic binaries were detected in the sample. We present first orbits for 67 systems and improved elements for another 64 previously published orbits, based on additional observations. For completeness, 25 published orbits are listed as well. The orbits are based on a total of 4039 observations, an average of 26 per system. Orbital periods range from 41.5 to 14722-days (40yrs), eccentricities from 0.00 to 0.81. The remaining systems have too long periods and/or inadequate phase coverage for an orbit determination at this time or too few observations.2007A&A...473..829Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/473/829CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/299/53 : Red giants in NGC 3680 and IC 4651 (Mermilliod+, 1995)J/A+A/307/80 : Velocities of red giants in NGC 2099 (Mermilliod+ 1996)J/A+A/319/481 : Radial velocities of 10 spectros. binaries (Mermilliod+ 1997)J/A+A/324/91 : Melotte 71 red giants radial velocities (Mermilliod+ 1997)J/A+A/339/423 : Velocities of red giants in NGC 752 (Mermilliod+ 1998)J/A+A/375/30 : Radial velocities in open clusters (Mermilliod+, 2001)J/A+A/399/105 : Radial velocities of red giants in NGC 1817 (Mermilliod+, 2003)J/A+A/423/189 : UBV and RV of red giants in NGC 2477 (Eigenbrod+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/473/829https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/473/829http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/473/829https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/473/829https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/473/829http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/473/829GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/473/829/catalog (Catalogue of orbital elements (tables 3-8 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/473/829/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/473/829/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/473/829/catalog?GETtext/xml+votable180.050000true26.322972.275708330.005555555555555556Cone search capability for table J/A+A/473/829/cfapos (Simbad position for stars with CfA data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/473/829/cfapos?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/473/829/cfapos?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/473/829/cfapos?GETtext/xml+votable180.050000true28.8137166737.8420250.0055555555555555566/1302 1325 1923 1930 2433 2436 2438 3045 3308 3384 3604 3796 3798 4298 4699 6149 13048 13198 14033 14056 20797 21369 21523 21531 21538 21557 21647 21774 22130 23538 23547 23639 24121 24522 28480 28711 28717 28838 29084 29533 30208 30215 30438-30439 30635 31812 37237 37707 37712 37721 37745 37859 37933 37944 37971 38242 38248 38432 39353 39356 39766 39770 39895 39901 40104 40490 40601 40696 41682 41789 41834 41878 42210 42216 42274 42377 42402 42583 43022https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/473/829?format=asciiOpticaldefaultJ/A+A/473/829/catalogCatalogue of orbital elements (tables 3-8 of paper)PerOrbital perioddtime.perioddoublerecnoRecord number assigned by the VizieR team.
