[Mesa-users] Definition of eta (electron degeneracy parameter)

To help avoid confusion, I'd also like to clarify that the eta assignment you found earlier is misleading:

> eta = (efermi - me*clight*clight)/(kerg*T)

This code snippet is coming from an assignment that is internal to the compton opacity routine in the kap module, and is distinct from the EOS code that sets the value of eta that is used in the star module.
