File formats
In this directory, you will find the tracks corresponding to the latest grids. Their output spectrum are available here, and the isochrones generated with the new models are available here. So far, only the solar metallicity is available.
There are four types of files:
- the evolution files;
- the isochrone files;
- the spectra files.
- the X-UV evolution files.
The names of the evolution files give information on the model considered:
- the mass stands after the M (M085: 85 M⊙; M2p5: 2.5 M⊙);
- 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.
The names of the spectra files give the following informations:
- the related model, with the same naming convention as above;
- the time-step number in 7 digits;
- the Tsurf and log(L/L⊙) of the model at that time step;
- the type of data provided:
- full spectrum = spec;
- normalised spectrum = norm;
- continuum only = cont.
The names of the X-UV evolution files give the following informations:
- the name of the host star of the planetary system;
- the initial value of the surface rotation rate;
- the type of rotator.
