The data are magnitude differences (Du,Dv,Db,Dy,D(b-y),Dm1,Dc1) of the variable star minus comparison star in the standard system versus Heliocentric Julian Day. The comparison star is HD 204626. The observations were carried out (by E. Rodriguez, J.M. Garcia, S. Martin and A. Claret) through the year 1998 using the 0.90m telescope at Sierra Nevada Observatory, Spain. This telescope is equipped with a six-channel uvby-Hbeta spectrograph photometer for simultaneous measurements in uvby or in the narrow and wide Hbeta channels, respectively.2001A&A...372..588Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/372/588CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/372/588https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/372/588http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/372/588https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/372/588https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/372/588http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/372/588GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/372/588/table1Light CurveHJDHeliocentric Julian Datedtime.epochdoublerecnoRecord number assigned by the VizieR team.
