cds-question@unistra.frglobular-star-clustersvariable-starsccd-photometryCCD time-series observations of the central region of the globular cluster NGC 3201 were obtained with the aim of performing the Fourier decomposition of the light curves of the RR Lyrae stars present in that field. This procedure gave the mean values, for the metallicity, of [Fe/H]_ZW_=-1.483+/-0.006 (statistical) +/-0.090 (systematical), and for the distance, 5.000+/-0.001kpc (statistical) +/-0.220 (systematical). The values found from two RRc stars are consistent with those derived previously. The differential reddening of the cluster was investigated and individual reddenings for the RR Lyrae stars were estimated from their V-I curves. We found an average value of E(B-V)=0.23+/-0.02. An investigation of the light curves of stars in the blue stragglers region led to the discovery of three new SX Phe stars. The period-luminosity relation of the SX Phe stars was used for an independent determination of the distance to the cluster and of the individual reddenings. We found a distance of 5.0kpc2014RMxAA..50..307Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RMxAA/50.307CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PAZh/22/269 : Giant branch and variable stars in NGC 3201 (Samus+, 1996)J/AJ/123/279 : VI Photometry and Variables in NGC 3201 (von Braun+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RMxAA/50.307https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RMxAA/50.307http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RMxAA/50.307https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RMxAA/50.307https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RMxAA/50.307http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RMxAA/50.307GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RMxAA/50.307/table1 (General data for all of the confirmed variables in NGC 3201 in the field of view of our images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RMxAA/50.307/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RMxAA/50.307/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RMxAA/50.307/table1?GETtext/xml+votable180.050000true154.4284167-46.44383330.0055555555555555566/384652.367228618189496e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RMxAA/50.307?format=asciiOpticaldefaultJ/other/RMxAA/50.307/table5VI photometry of 34 RR Lyrae, 14 SX Phe, 1 SR and 1 eclipsing binary in NGC 3201recnoRecord number assigned by the VizieR team.
