cds-question@unistra.frmetallicityinfrared-photometryvisible-astronomybroad-band-photometrym-starsA collection of Johnson/Cousins photometry for stars with known [Fe/H] is used to generate color-color relations that include the abundance dependence. Literature temperature and bolometric correction (BC) dependences are attached to the color relations. The JHK colors are transformed to the Bessell & Brett (1988PASP..100.1134B) homogenized system. The main result of this work is the tabulation of seven colors and the V-band BC as a function of Teff, logg, and [Fe/H] for -1.06<V-K<10.2 and an accompanying interpolation program. Improvements to the present calibration would involve filling photometry gaps, obtaining more accurate and on-system photometry, knowing better logg and [Fe/H] values, improving the statistics for data-impoverished groups of stars such as metal-poor K dwarfs, applying small tweaks in the processing pipeline, and obtaining better empirical temperature and BC relations, especially for supergiants and M stars. A way to estimate dust extinction from M dwarf colors is pointed out.2011ApJS..193....1Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/193/1CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/442/281 : Late-type giants BVRIJHKL and Teff calibration (Kucinskas+J/A+A/458/293 : Temperature calibration for A + mid F-type stars (Paunzen+J/MNRAS/371/1793 : Metallicity calibrations for UBV photometry (Karatas+ 2006)http://astro.wsu.edu/models/ : Supporting data for this paperhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/193/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/193/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/193/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/193/1https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/193/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/193/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJS/193/1/table3Colors and bolometric correction summary tablerecnoRecord number assigned by the VizieR team.
