Dear all

I intend to investigate on the effects of stellar mass (M ) and metallicity (Z ) on distribution in the C-O white dwarfs by calculating stellar evolution from the main-sequence through
the end of the second dredge-up for M  = 3  and Z  = 0.02.
I ran 1M_pre_ms_to_wd program and I saw production of C and O in the core of star. I want to plot these outputs for c-o core mass 'Y-axis’ , M(ms) of star ‘ X axis '
but when I achieve outputs for LOGS and  plot in the Mesaplot with python program, I can’t plot it. as follows 



so I don’t know that:
1-Do I chose program of 1M_pre_ms_to_wd correctly of this subject?
2- Do I must add other cods for this program ‘1M_pre_ms_to_wd’
3-is way for plotting these output correct? if not correct please let me to know.

please guide me.

best wishes
Sanaz
