[Mesa-users] Adding and swapping atmosphere tables

[Giovanni Mirouh]

Dear all,

I am sorry to insist, but I would really be grateful for any opinion 
from the community: is there a better way to include new atmosphere 
tables than making changes to the atmosphere fortran routines?

My original email is below for more details, I thank you all in advance 
for any pointers you could give me.
Best.
