[Mesa-users] How to extract values

[Rob Farmer]

So its a function that is in MESA_DIR/star/public/star_lib.f90.

So first make sure you have
use star_lib
so you can call the function.

It has a function arguments:

      real(dp) function star_get_profile_output(s,name,k)
         type (star_info), pointer :: s
         character(len=*),intent(in) :: name
         integer,intent(in) :: k

So you just need to pass (s, the name of the column you want, the zone you
want that value at) and you'll get back that value for the column you asked
for.
