This doesn't seem trivial to me.  As far as I know, this information is
not part of the star structure, and therefore not easy to access from

That being said, what exactly do you want to achieve?  I'm not sure I
understand what "actually implemented" means.

If you're worried about checking the details of specific rates, I think
the way to do that is /not/ to print out reaction rates from a full star
MESA calculation, but rather to call the rates (or net) module directly.

There are examples of how to do this sort of thing in the test
directories in the rates (or net) modules.  In particular, the file


may be of interest to you.
