cds-question@unistra.fropen-star-clustersvariable-starsvisible-astronomybroad-band-photometryPhotoelectric, photographic and CCD UBV photometry, spectroscopic observations and star counts are presented for the open cluster Berkeley 58 to examine a possible association with the 4.37d Cepheid CG Cas. The cluster is difficult to separate from the early-type stars belonging to the Perseus spiral arm, in which it is located, but has reasonably well-defined parameters: an evolutionary age of ~10^8^yr, a mean reddening of E(B-V)(B0)=0.70+/-0.03 s.e. and a distance of 3.03+/-0.1kpc (V_0_-M_V_=12.40+/-0.12 s.d.). CG Cas is a likely cluster coronal member on the basis of radial velocity, and its period increase of +0.170+/- 0.01s/y and large light amplitude describe a Cepheid in the third crossing of the instability strip lying slightly blueward of strip centre. Its inferred reddening and luminosity are E(B-V)=0.64+/-0.02 s.e. and <M_V_>=-3.06+/-0.12. A possible K supergiant may also be a cluster member.2008MNRAS.388..444Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/388/444CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/113/2104 : UBV photometry of 163 stars around SU Cyg (Turner+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/388/444https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/388/444http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/388/444https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/388/444https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/388/444http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/388/444GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/388/444/tables (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/388/444/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/388/444/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/388/444/tables?GETtext/xml+votable180.050000true0.246833360.95902780.0055555555555555566/3050 14293https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/388/444?format=asciiOpticaldefaultJ/MNRAS/388/444/tablesCombined table from original tablesrecnoRecord number assigned by the VizieR team.
