An empirical approach to the location of the theoretical isochrones in the observational plane
A new empirical calibration of the (B-V) index versus the three fundamental stellar parameters T(eff), (Fe/H), and log g is presented whose range of validity is adequate to analyze the main sequence and turnoff regions of most of the stellar cluster systems. Significant systematic differences are found between this new calibration and previous ones
