[Mesa-users] About datasets related to HR diagram

[Ebraheem Farag]

Thanks Nathali,

Using history.data 'log_Lnuc', 'log_L', and 'center_h1'
For ZAMS: you can mark the point on each model where Lnuc /L >= 0.99, then
plot a line through these points.
For TAMS: you can mark the point on each model where center_h1 <= 1d-4,
then plot a line through these points.

Does this help?
