cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe present new B, V and I CCD time-series photometry for 177 variable stars in a 13x13arcmin^2^ field centred on the globular cluster M54 using the European Southern Observatory (ESO)-Danish 1.54-m telescope in La Silla, 94 of which are newly identified variables. The total sample is composed of two anomalous Cepheids, 144 RR Lyrae stars (108 RR0 and 36 RR1), three SX Phoenicis, seven eclipsing binaries (five W UMa and two Algol binaries), three variables of uncertain classification and 18 long-period variables. Ephemerides are provided for all the observed short-period variables. The positional accuracy is better than 0.2".2010MNRAS.406..329Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/406/329CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/109/1086 : VI Photometry in M54 and Sgr Dwarf Galaxy (Sarajedini+ 1995)J/AJ/118/1245 : Elemental abundances in five stars in M54 (Brown+, 1999)J/AJ/119/1760 : M54 and Sgr dSph VI photometry (Layden+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/406/329https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/406/329http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/406/329https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/406/329https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/406/329http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/406/329GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/406/329/table1 (M54 variables catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/406/329/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/406/329/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/406/329/table1?GETtext/xml+votable180.050000true283.79063306-30.476806110.0055555555555555566/480352.2537631428488926e-19 5.046557045242342e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/406/329?format=asciiOpticalInfrareddefaultJ/MNRAS/406/329/table1M54 variables catalogrecnoRecord number assigned by the VizieR team.
