Abstract: We extend the calibration of the (λ_{1},D) parameters of the BCD spectrophotometric system for Teff and logg in order to include the luminosity classes I and II. We select a set of 112 objects and calculate the effective temperatures and logg for each of them using integrated fluxes, several distance determinations and evolutionary tracks. We fit then the curves of constant Teff and log g using the calculated set of (Teff, logg) values together with the measurements of (λ_{1},D) parameters taken from low resolution spectra.
