Scientific paper

A new, semiempirical calibration of the two reddening-free parameters X and Y of Geneva photometry in terms of effective temperature and gravity is proposed. The calibration is based on Kurucz's grid of atmosphere models and on a set of fundamental stars; it is valid for main sequence stars with Te equal to or greater than 10,000 K. Theoretical evolutionary tracks were then used to calibrate the Y vs X diagram in terms of stellar mass, for M equal to or greater than 2.5 - 3.0 solar masses.
