cds-question@unistra.fropen-star-clustersvisible-astronomybroad-band-photometryproper-motionsThe results of astrometric and photometric investigations of the open cluster NGC 7243 are presented. Proper motions of 2165 stars with root-mean-square error of 1.1mas/yr were obtained by means of PDS scanning of astrometric plates covering the time interval of 97 years. A total of 211 cluster members down to V=15.5mag have been identified. V and B magnitudes have been determined for 2118 and 2110 stars respectively. Estimations of mass 348M_{sun}_<M<522M_{sun}_, age t=2.510^8^yr, distance r=698pc and reddening E(B-V)=0.24 of the cluster NGC 7243 have been made.2003A&A...401..531Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/401/531CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/376/441 : Absolute proper motions of 112 open clusters (Dias+, 2001)J/A+AS/146/251 : Absolute proper motions of open clusters (Baumgardt+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/401/531https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/401/531http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/401/531https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/401/531https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/401/531http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/401/531GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/401/531/table8 (Star positions, proper motions, BV photometry, and membership probabilities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/531/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/531/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/531/table8?GETtext/xml+votable180.050000true332.678583349.29422220.0055555555555555566/14039 14045 14047 14208 14210-14211 14216-14218https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/401/531?format=asciiOpticaldefaultJ/A+A/401/531/table8Star positions, proper motions, BV photometry, and membership probabilitiesrecnoRecord number assigned by the VizieR team.
