Abstract:
    The table provides improved numerical relations between effective
    temperatures of stars, their B-V colors, and their bolometric
    corrections (BC) for the purpose of comparing theoretical stellar
    evolutionary calculations to color-magnitude diagrams of star
    clusters. Temperature and bolometric correction measurements for
    335 stars from the literature form the observational basis for the
    transformations. Measured temperatures range from 2900 to 52500K.
