  In view of the importance of accurate fundamental stellar parameters for
`Spectro-photometric dating of stars and galaxies", we present simultaneous
effective temperature and metallicity determinations for a sample of 40 stars
from Stromgren synthetic photometry with an empirically calibrated grid of
model atmosphere spectra (BaSeL models). Comparisons with Ribas et al.'s (1998)
results, using Hipparcos parallaxes, for 8 binaries of our working sample are
presented, showing good agreement with the most reliable parallaxes, and giving
hence a significant weight to the validity of the BaSeL models for synthetic
photometry applications.
