cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe have developed a maximum-likelihood procedure to fit theoretical isochrones to the observed cluster color-magnitude diagrams of NGC6866, an open cluster in the Kepler spacecraft field of view. The Markov chain Monte Carlo algorithm permits exploration of the entire parameter space of a set of isochrones to find both the best solution and the statistical uncertainties. For clusters in the age range of NGC6866 with few, if any, red giant members, a purely photometric determination of the cluster properties is not well-constrained. Nevertheless, based on our UBVRI photometry alone, we have derived the distance, reddening, age, and metallicity of the cluster and established estimates for the binary nature and membership probability of individual stars. We derive the following values for the cluster properties: (m-M)_V_=10.98+/-0.24, E(B-V)=0.16+/-0.04 (so the distance=1250pc), age=705+/-170Myr, and Z=0.014+/-0.005.2014AJ....147..139Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/147/139CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/322 : UCAC4 Catalogue (Zacharias+, 2012)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/MNRAS/429/1466 : Kepler stars in the NGC 6866 field (Balona+, 2013)J/AJ/145/7 : UBVRI photometry of the open cluster NGC 6811 (Janes+, 2013)J/AJ/142/112 : KIC photometric calibration (Brown+, 2011)J/PAZh/36/354 : NGC 6866 proper motions and CCD photometry (Frolov+, 2010)J/AcA/59/193 : BV photometry of stars in NGC 6866 (Molenda-Zakowicz+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/147/139https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/147/139http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/147/139https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/147/139https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/147/139http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/147/139GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/147/139/table2 (Photometric catalog in the region of NGC 6866)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/147/139/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/147/139/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/147/139/table2?GETtext/xml+votable180.050000true300.467992244.44282190.0055555555555555566/14749 14751 14792 147943.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/147/139?format=asciiOpticalInfrareddefaultJ/AJ/147/139/table2Photometric catalog in the region of NGC 6866recnoRecord number assigned by the VizieR team.
