cds-question@unistra.frglobular-star-clustersproper-motionsinfrared-photometryvisible-astronomybroad-band-photometryUsing astrometric techniques developed by Anderson et al., we determine proper motions (PMs) in the ~14.60x16.53arcmin^2^ area of the kinematically "thick-disk" globular cluster M12. The cluster's proximity and sparse nature makes it a suitable target for ground-based telescopes. Archive images with time gap of ~11.1-years were observed with the wide-field imager (WFI) mosaic camera mounted on the ESO 2.2m telescope. The median value of PM error in both components is ~0.7mas/yr for the stars having V<=20mag. PMs are used to determine membership probabilities and to separate field stars from the cluster sample. In electronic form, a membership catalog of 3725 stars with precise coordinates, PMs and BV RI photometry is being provided. One of the possible applications of the catalog is demonstrated by gathering the membership information of the variable stars, blue stragglers and X-ray sources reported earlier in the cluster's region.2018RAA....18..126Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/18.126CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/608/243 : CCD BVI photometry of M12 stars (Hargis+, 2004)J/A+A/464/939 : Abundances of red giants in NGC 6218 (Carretta+, 2007)J/AcA/62/357 : Proper motions in 6 globular clusters (Zloczewski+, 2012)J/ApJ/791/39 : NGC 6218 and NGC 5904 lithium abundances (D'Orazi+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/18.126https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/18.126http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/18.126https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/18.126https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/18.126http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/18.126GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/18.126/table4 (Membership catalog for M12)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/18.126/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/18.126/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/18.126/table4?GETtext/xml+votable180.050000true251.8460417-2.02580560.0055555555555555566/311152.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/18.126?format=asciiOpticalInfrareddefaultJ/other/RAA/18.126/table4Membership catalog for M12recnoRecord number assigned by the VizieR team.
