cds-question@unistra.frmagellanic-cloudsvariable-starsphotometryWe present a careful and detailed light curve analysis of RR Lyrae stars in the Small Magellanic Cloud (SMC) discovered by the Optical Gravitational Lensing Experiment (OGLE) project. Out of 536 single-mode RR Lyrae stars selected from the data base, we have investigated the physical properties of 335 'normal-looking' RRab stars and 17 RRc stars that have good quality photometric light curves. We have also been able to estimate the distance modulus of the cloud which is in good agreement with those determined from other independent methods.2010MNRAS.402..691Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/402/691CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/138/1661 : The Araucaria Project: RR Lyrae in SMC (Szewczyk+, 2009)J/AcA/48/113 : OGLE RR Lyrae VI photometry (Udalski, 1998)J/AcA/60/165 : VI light curves of SMC RR Lyrae (Soszynski+, 2010)J/MNRAS/415/1366 : OGLE RR Lyrae in SMC (Kapakos+, 2011)J/MNRAS/426/2063 : SMC RR Lyrae Fourier decomposition (Kapakos+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/402/691https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/402/691http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/402/691https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/402/691https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/402/691http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/402/691GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/402/691/table1 (Fourier parameters for 478 fundamental mode (RRab) SMC RR Lyr variables in the OGLE data base (I-band data))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/691/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/691/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/691/table1?GETtext/xml+votable180.050000true12.006625-73.50597220.005555555555555556Cone search capability for table J/MNRAS/402/691/table2 (Fourier parameters for 58 overtone mode (RRc) SMC RR Lyr variables in the OGLE data base (I-band data))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/691/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/691/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/691/table2?GETtext/xml+votable180.050000true15.586125-72.63155560.0055555555555555566/33294-33295 33304 33306 33316-33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/402/691?format=asciidefaultJ/MNRAS/402/691/table1Fourier parameters for 478 fundamental mode (RRab) SMC RR Lyr variables in the OGLE data base (I-band data)recnoRecord number assigned by the VizieR team.
