[mesa-users] Correlating time step numbers and profile.data outputs

Take a look at the file in LOGS called "profiles.index".

For each profile, there is a line in profiles.index giving the model
number, its priority, and its profile number.

So a line in that file like

        425           1          57

means look at profile57.data to find the output from step 425.

The middle number is the priority.  Priority level 2 is for models saved
because of some special event in the evolution such as the onset of
helium burning. Priority level 1 is for models saved because the number
of models since the most recent profile has reached the currently
setting of the profile_interval parameter.

Hope that helps.

Best,
Josiah
