Colors are tabulated for Johnson U-V and B-V, Cousins V-R and V-I, Johnson-Glass V-K, J-K, and H-K, and CIT/CTIO V-K, J-K, H-K, and CO. We have developed these color-temperature relations by convolving synthetic spectra with the best-determined, photometric filter transmission profiles. The synthetic spectra have been computed with the SSG spectral synthesis code (Bell & Gustafsson 1978; Gustafsson & Bell 1979) using MARCS stellar atmosphere models (Gustafsson et al. 1975; Bell et al. 1976) as input. Both of these codes have been improved substantially, especially at low temperatures, through the incorporation of new opacity data. The resulting synthetic colors have been put onto the observational systems by applying color calibrations derived from models and photometry of field stars that have effective temperatures determined by the infrared flux method. These color calibrations have zero points that change most of the original synthetic colors by less than 0.02 mag, and the corresponding slopes generally alter the colors by less than 5%.2000AJ....119.1448Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/119/1448CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/469/355 : Teff, B-V and BC relation (Flower, 1996)J/AJ/119/1424 : Color-temperature relations of M giants (Houdashelt+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/119/1448https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/119/1448http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/119/1448https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/119/1448https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/119/1448http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/119/1448GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/119/1448/table2 (Field star sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/119/1448/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/119/1448/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/119/1448/table2?GETtext/xml+votable180.050000true2.8160719-15.46797750.0055555555555555566/341 737 915 1341 1360 1535 2472 2476 2837 3020 3036 3102 3118 4438 4559 5245 5535 5587 6126 6219 6339 7402 7610 8476 8671 8767 8845 8985 9083 9125 9127 9213 9520 9610 9717 9835 10375 10899 12962 13231 13301 13333 13882 14278 14632 14917 15174 15597 15715 16069 17171 18166 18227 18591 20178 20518 20981 21060 22015 22300 22708 23190 23369 23540 23695 24151 24799 25869 26633 26959 26975 27568 28151 28487 28605 28968 29024 30234 30339 30518 30529 31187 31475 31478 31576 31784 32645 33281 34664 36446 36564 36693 36697 40795 44485 44554 44883 45485 46131https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/119/1448?format=asciiOpticalInfrareddefaultJ/AJ/119/1448/table2Field star samplerecnoRecord number assigned by the VizieR team.
