dc.descriptionIn 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.
