cds-question@unistra.frglobular-star-clustersproper-motionsinfrared-photometryvisible-astronomybroad-band-photometryWith a high value of heliocentric radial velocity, a retrograde orbit, and suspected to have an extragalactic origin, NGC 3201 is an interesting globular cluster for kinematical studies. Our purpose is to calculate the relative proper motions (PMs) and membership probability for the stars in the wide region of globular cluster NGC 3201. PM based membership probabilities are used to isolate the cluster sample from the field stars. The membership catalog will help address the question of chemical inhomogeneity in the cluster. Archive CCD data taken with a wide-field imager (WFI) mounted on the ESO 2.2m telescope are reduced using the high-precision astrometric software developed by Anderson et al. for the WFI images. The epoch gap between the two observational runs is ~14.3 years. To standardize the BVI photometry, Stetson's secondary standard stars are used. The CCD data with an epoch gap of ~14.3 years enables us to decontaminate the cluster stars from field stars efficiently. The median precision of PMs is better than ~0.8mas/yr for stars having V<18mag that increases up to ~1.5mas/yr for stars with 18<V<20mag. Kinematic membership probabilities are calculated using PMs for stars brighter than V~20mag. An electronic catalog of positions, relative PMs, BVI magnitudes, and membership probabilities in the ~19.7x17arcmin^2^ region of NGC 3201 is presented. We use our membership catalog to identify probable cluster members among the known variables and X-ray sources in the direction of NGC 3201.2017AJ....153..134Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/134CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/ApJ/801/69 : EWs for giant star members of NGC3201 (Mucciarelli+, 2015)J/A+A/584/A59 : Proper motions and membership in NGC 6366 (Sariya+, 2015)J/other/RMxAA/50.307 : RR Lyr light curves in NGC 3201 (Arellano Ferro+, 2014)J/MNRAS/430/3350 : Proper motions and membership in NGC 3766 (Yadav+, 2013)J/AcA/62/357 : Proper motions in 6 globular clusters (Zloczewski+, 2012)J/A+A/543/A87 : Stars proper motions and photometry in M55 (Sariya+, 2012)J/A+A/497/371 : UBVI photometry of NGC 3201 (Kravtsov+, 2009)J/A+A/484/609 : BVI photometry and proper motions in M67 (Yadav+, 2008)J/A+A/445/155 : XMM count-rates in M 55 and NGC 3201 (Webb+, 2006)J/AJ/123/279 : VI Photometry and Variables in NGC 3201 (von Braun+, 2002)J/A+AS/131/89 : NGC 1750 + NGC 1758 proper motions (Tian+ 1998)J/ApJ/454/788 : Radial velocities and BV photometry of NGC 3201 (Cote+ 1995)J/ApJS/90/83 : Binaries in NGC 3201 (Cote+, 1994)http://archive.eso.org/eso/eso_archive_main.html : ESO Science Archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/153/134https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/153/134http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/153/134https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/153/134https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/153/134http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/153/134GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/153/134/table4 (The membership catalog for NGC 3201)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/153/134/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/153/134/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/153/134/table4?GETtext/xml+votable180.050000true154.4327917-46.61363890.0055555555555555566/384652.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/153/134?format=asciiInfraredOpticaldefaultJ/AJ/153/134/table4The membership catalog for NGC 3201recnoRecord number assigned by the VizieR team.
