In this directory, you will find the tracks corresponding to the new grids, and to the isochrones generated with the new models. So far, only the solar metallicity is available.
There are two types of files:
the evolution files;
the isochrone files.
The names of the evolution files give information on the model considered:
the mass stands after the M (M085: 85 Msol; M2p5: 2.5 Msol);
the metallicity stands after the Z (Z14: Z=0.014; Z02: Z=0.002);
the rotation rate stands after the V (V0: no rotation; V4: V/Vcrit=0.40)
The names of the isochrone files give the following informations:
the metallicity stands after the Z;
the rotation rate considered is indicated after the V;
the log (age) stands after the t.
