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) $_{\rm J}$ (RI) $_{\rm C}$ JHKLL $^\prime$ 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 $M_{\odot}$and metallicities Z=0.0004 (1/50 $Z_{\odot}$) to 0.1 (5 $Z_{\odot}$). 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 $M_{\odot}$ calculated with the Geneva stellar evolution code.
