Abstract:
    A 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.
