cds-question@unistra.frchemical-abundancesopen-star-clustersWe present metallicity estimates for seven open clusters based on spectrophotometric indices from moderate-resolution spectroscopy. Observations of field giants of known metallicity provide a correlation between the spectroscopic indices and the metallicity of open cluster giants. We use 2 analysis to fit the relation of spectrophotometric indices to metallicity in field giants. The resulting function allows an estimate of the target-cluster giants' metallicities with an error in the method of +/-0.08 dex. We derive the following metallicities for the seven open clusters: NGC 1245, [M/H]=-0.14+/-0.04; NGC 2099, [M/H]=+0.05+/-0.05; NGC 2324, [M/H]=-0.06+/-0.04; NGC 2539, [M/H]=-0.04+/-0.03; NGC 2682 (M67), [M/H]=-0.05+/-0.02; NGC 6705, [M/H]=+0.14+/-0.08; NGC 6819, [M/H]=-0.07+/-0.12. These metallicity estimates will be useful in planning future extrasolar planet transit searches, since planets may form more readily in metal-rich environments.2005AJ....130.1916Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/1916CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/376/561 : Rc light curves of 7 variables in M37 (Kiss+, 2001)J/A+A/307/80 : Velocities of red giants in NGC 2099 (Mermilliod+ 1996)J/A+A/418/979 : VI and CT1 photometry in NGC 2324 field (Piatti+, 2004)J/A+A/361/945 : UBV photometry in open cluster NGC 2539 (Lapasset+, 2000)J/AJ/106/181 : CCD photometry of open cluster M67 (Montgomery+ 1993)III/221 : Catalogue of [Fe/H] of F, G, K stars (Cayrel de Strobel+ 2001)WEBDA : http://www.univie.ac.at/webda/navigation.htmlhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/1916https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/1916http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/1916https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/1916https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/1916http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/1916GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/1916/indices (Metallicity indices for calibration and target stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/1916/indices?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/1916/indices?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/1916/indices?GETtext/xml+votable180.050000true165.931953161.75103330.0055555555555555566/1218 1603 3091 4298 4506 4698 6051 6126 6166 6210 6219 6825 7131 8333 9083 10266 10886 12111 14752 14754 15012 15511 15597 22130 23533 23695 24374 24420 24522 26380 26457 26538 26552 27082 27444 27752 30215 40222 40696 44518 45050https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/1916?format=asciiOpticaldefaultJ/AJ/130/1916/indicesMetallicity indices for calibration and target starsrecnoRecord number assigned by the VizieR team.
