Abstract
Using the Kurucz model atmospheres as a guide, the author calibrates effective temperatures and bolometric corrections for early-type stars in terms of the Strömgren c0 and β indices. These are placed on an empirical scale by adjusting the zero points for best agreement with measurements by Code et al. The form of the mass calibration is determined from evolutionary calculations and the zero point adjusted for best agreement with empirical determinations. A mass discrepancy problem arises when these masses are compared with those determined from model atmospheres.Keywords
