cds-question@unistra.frvariable-starsinfrared-photometryvisible-astronomyphotometryDM Cyg, a fundamental mode RRab star, was observed in the 2007 and 2008 seasons in the framework of the Konkoly Blazhko Survey. Very small amplitude light-curve modulation was detected with 10.57d modulation period. The maximum brightness and phase variations do not exceed 0.07mag and 7min, respectively. In spite of the very small amplitude of the modulation, beside the frequency triplets characterizing the Fourier spectrum of the light curve, two quintuplet components were also identified. The accuracy and the good phase coverage of our observations made it possible to analyse the light curves at different phases of the modulation separately.2009MNRAS.397..350Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/397/350CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/397/350https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/397/350http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/397/350https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/397/350https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/397/350http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/397/350GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/MNRAS/397/350/table1Time series of the CCD BVIc magnitude and B-V, V-Ic colour index differences of DM CygrecnoRecord number assigned by the VizieR team.
