cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryvisible-astronomybroad-band-photometryWe present new BVI CCD photometry for variables in the globular cluster M15. Our photometry was obtained using both the image subtraction package ISIS and DAOPHOT/ALLFRAME. The data were acquired in 2001 on two observing runs on 11 observing nights using the 2m telescope of the Bulgarian National Astronomical Observatory "Rozhen" with a Photometrics CCD camera. For 39 previously known variables, we present a period for the first time, and improved periods were obtained for many previously known variables. Fourteen new variables are reported. We present updated Bailey diagrams for the cluster, and discuss its Oosterhoff classification. Although many of M15's RRab pulsators fall at an intermediate locus between Oosterhoff types I and II (OoII) in the Bailey diagram, we argue that M15 is indeed a bona fide OoII globular cluster.2008AJ....135.1459Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/1459CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/110/704 : RR Lyrae Variables in M15 (Silbermann+ 1995)J/AJ/124/3255 : UBV photometry in M15 (van der Marel+, 2002)J/other/RMxAA/42.75 : M15 RR Lyrae CCD RV light curve (Arellano Ferro+, 2006)J/ApJ/670/379 : UV photometry of M15 (Dieball+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/1459https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/1459http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/1459https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/1459https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/1459http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/1459GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/1459/table1 (M15 variables, new periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1459/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1459/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1459/table1?GETtext/xml+votable180.050000true322.459166712.17413890.0055555555555555566/12405https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/1459?format=asciiOpticalInfrareddefaultJ/AJ/135/1459/table1M15 variables, new periodsTypeVariable typemeta.code;src.varcharrecnoRecord number assigned by the VizieR team.
