cds-question@unistra.frvariable-starsinfrared-photometryvisible-astronomyWide-band photometryccd-photometryA total of total of 1071 B, V, Ic-band CCD frames are taken for three GCVS RR Lyr-type variables (CL Eri, CM Eri, and CN Eri), for which only coordinates were known. Observations were made with the 76-cm telescope of the South African Astronomical Observatory using an SBIG CCD ST-10XME. The inferred periods and light-curves confirm that CL Eri (P=0.644d), which was found to exhibit the Blazhko effect, and CN Eri (P=0.580d) are RR Lyr-type variables. CM Eri is most probably a Population-Il Cepheid with a period of 0.824d.2011Obs...131..315Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Obs/131.315CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2012)J/other/Obs/131.386 : BVIc phot. of 8 RR Lyr-type stars (Berdnikov+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Obs/131.315https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Obs/131.315http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Obs/131.315https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Obs/131.315https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Obs/131.315http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Obs/131.315GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/other/Obs/131.315/table1Photoelectric observations of RR Lyrae type starsrecnoRecord number assigned by the VizieR team.
