cds-question@unistra.frglobular-star-clustersvariable-starsccd-photometryWe present time-series data on the variable stars of the galactic globular cluster Messier 3 (M3). We give BVI_C_ light curves for 226 RR Lyrae, 2 SX Phe and 1 W Vir type variables, along with estimated fundamental photometric parameters such as intensity and magnitude-averaged brightness and pulsation periods. In some cases, the periods we have found significantly differ from the previously published ones. This is the first published light curve and period determination for variable V266. The I-band light curve has not been observed previously for numerous (76) variables. Three new RR Lyrae variables have been discovered. Groups of RR Lyrae variables that belong to different evolutionary stages and have been separated previously on the basis of V data were found here for all colours and colour indices by cluster analysis. The I-band period-luminosity relation is also discussed. From the 66 modulated (Blazhko type) RR Lyrae stars we investigated, six are newly identified and two of them are first overtone pulsators. In the case of 13 RR Lyrae, the period of Blazhko cycle has been estimated for the first time. V252 is identified as a new RRd variable. Amplitude ratios of RRd stars have been investigated to search possible mode content changes. In contrast to previous publications no changes have been found. Problems with the sampling of the time-series of typical cluster variability surveys are demonstrated.2006MNRAS.372.1657Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/372/1657CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/278 : Catalog of stars in M3 (von Zeipel, 1908)J/A+A/290/69 : M3 photographic photometry (Buonanno+, 1994)J/A+A/320/757 : M3 stars CCD photometry (Ferraro+ 1997)J/A+A/324/915 : Blue stragglers in M3 (Ferraro+ 1997)J/AJ/108/1786 : Blue stragglers + variable stars in M3 (Guhathakurta+, 1994)J/AJ/120/1364 : Abundances in M3 and M13 (Cavallo+, 2000)J/AJ/122/3219 : M3 and M13 CCD BV photometry (Rey+, 2001)J/AJ/129/267 : RR Lyrae variables in NGC 5272 (Cacciari+, 2005)J/AJ/129/303 : Abundances of stars in M3 and M13 (Cohen+, 2005)J/AJ/129/1596 : BVI photometric variability survey of M3 (Hartman+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/372/1657https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/372/1657http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/372/1657https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/372/1657https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/372/1657http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/372/1657GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/372/1657/table3 (The basic parameters of the variables in M3)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/372/1657/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/372/1657/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/372/1657/table3?GETtext/xml+votable180.050000true205.546629228.34268060.0055555555555555566/10336-10337https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/372/1657?format=asciiOpticaldefaultJ/MNRAS/372/1657/table3The basic parameters of the variables in M3recnoRecord number assigned by the VizieR team.
