Abstract

We have used an updated version of the empirically and semi-empirically calibrated BaSeL library of synthetic stellar spectra of Lejeune et al. (1997, 1998) and Westera et al. (1999) to calculate synthetic photometry in the (UBV)_J - (RI)C - JHKLL'M, HST-WFPC2, Geneva, and Washington systems for the entire set of non-rotating Geneva stellar evolution models covering masses from 0.4--0.8 to 120--150 MO and metallicities Z=0.0004 (1/50 ZO) to 0.1 (5 ZO).

The results are provided in a database which includes all individual stellar tracks and the corresponding isochrones covering ages from 103 yr to 16--20 Gyr in time steps of Delta log t= 0.05 dex. The database also includes a new grid of stellar tracks of very metal-poor stars (Z=0.0004) from 0.8 -- 150 MO calculated with the Geneva stellar evolution code. The full database will be available in electronic form at the CDS http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/(vol)/(page)
