[Mesa-users] Question about scaling carbon rates

[Rob Farmer]

Hi
Which rate you need depends on your choice of nuclear network. Use
show_net_reactions_info = .true. in star_job to see the full detailed list.

I'm guessing you are using an approx net? in which case you want r1212

> rates/private/rates_names.f90

I'm glad you're looking into the code, unfortunately many rates aren't
listed in the code explicitly as they get generated at runtime so you'll
need to use show_net_reactions_info. Only reactions that need some sort of
special handling are listed in the code.
