Description:
This database was created from an updated version of the empirically
and semi-empirically calibrated BaSeL library of synthetic stellar
spectra of Lejeune et al. (1997, Cat. J/A+AS/125/229, 1998, Cat.
J/A+AS/130/65) and Westera et al. (1999, ASP Conference Series 192,
203-206) 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 120-150M☉ and metallicities Z=0.0004 (1/50Z☉)
to 0.1 (5Z☉). The results are provided in a database which
includes all individual stellar tracks and the corresponding
isochrones covering ages from 103yr to 16-20Gyr in time steps of
Δlogt=0.05dex. The database also includes a new grid of stellar
tracks of very metal-poor stars (Z=0.0004) from 0.8-150M☉
calculated with the Geneva stellar evolution code.
The complete stellar grids are tabulated in the files table1.dat
(summary), evol.dat (evolutionary models), and in the files
ubv.dat, hst.dat, gen.dat and cmt.dat (synthetic colors in the
different photometric systems). These grids are also available as
mod* files in subdirectories evol, ubv, hst, gen and cmt.
The isochrones for the different photometric systems are summarized in
the file table2.dat; the parameters of the isochrones are tabulated in
the file iso.dat, the detailed isochrones being available as files iso*
in the subdirectories ubv, hst, gen and cmt.

Copied at http://webast.ast.obs-mip.fr/stellar/
* 23-Oct-2002: evolution models are also available in
the subdirectory "evol"
* 05-Oct-2003: the labels of the columns logTeff, logg, logL were
inadvertantly mixed in the description of the files cmt.dat,
gen.dat, hst.dat, ubv.dat; the problem was fixed.
