cds-question@unistra.fropen-star-clustersradial-velocityWe present the results of our ongoing radial-velocity (RV) survey of the old (7Gyr) open cluster NGC 188. Our WIYN 3.5m data set spans a time baseline of 11 years, a magnitude range of 12<=V<=16.5 (1.18-0.94M_{sun}_), and a 1{deg} diameter region on the sky. With the addition of a Domain Astrophysical Observatory data set we extend our bright limit to V=10.8 and, for some stars, extend our time baseline to 35 years. Our magnitude limits include solar-mass main-sequence stars, subgiants, giants, and blue stragglers (BSs), and our spatial coverage extends radially to 17pc (~13 core radii). For the WIYN data we present a detailed description of our data reduction process and a thorough analysis of our measurement precision of 0.4km/s for narrow-lined stars. We have measured radial velocities for 1046 stars in the direction of NGC 188, and have calculated RV membership probabilities for stars with >=3 measurements, finding 473 to be likely cluster members.2008AJ....135.2264Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/2264CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/122/1486 : NGC 2451A proper motions and membership (Platais+, 2001)J/AJ/124/601 : Absolute positions & proper motions in NGC 188 (Platais+, 2002)J/AJ/126/2922 : Astrometry and membership in NGC 188 (Platais+, 2003)J/A+A/461/509 : Membership and spectroscopy of IC 2391 (Platais+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/2264https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/2264http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/2264https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/2264https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/2264http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/2264GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/2264/table2 (Radial velocity data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/2264/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/2264/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/2264/table2?GETtext/xml+votable180.050000true6.202937585.570655560.0055555555555555565/1019 6/40753.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/2264?format=asciiOpticaldefaultJ/AJ/135/2264/table2Radial velocity datarecnoRecord number assigned by the VizieR team.
