我们使用了Lejeune等人([Cite]，[Cite])和Westa等人([Cite])的经验和半经验校准的B a S e L合成恒星光谱的更新版，在(UBV)J(RI)C JHKLL‘M，HST-WFPC2，日内瓦，计算了合成光度学，和华盛顿系统的全套非自转日内瓦恒星演化模型，质量从0.4-0.8到12 0-15 0美元，金属度$Z=0.0004$(1/5 0$Z\oot}$)到0.1(5$Z\odt}$)。结果在一个数据库中提供，该数据库包括所有单独的恒星轨迹和相应的等时线，涵盖的年龄从10.3年到16-20Gyr，时间步长为$\Delta\logt=$0.05Dex。该数据库还包括一个新的恒星轨迹网格，其中包括非常贫金属的恒星($Z=0.0004$)，这些恒星轨迹是用日内瓦恒星演化代码计算的$0.8150$$M0ot}$。
We have used an updated version of the empirically and semi-empirically calibrated B a S e L library of synthetic stellar spectra of Lejeune et al.([CITE], [CITE]) and Westera et al.([CITE]) 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 $M_{\odot}$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 10 3 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.
