The electron-positron portion of the two equations of state are identical. Differences between the two EOS routines originate from the model used for nucleons (interacting nucleons in a liquid dropish model versus non-interacting Boltzmann nucleons), and the model used for the composition.

Since the baryons in the NSE-based model are a perfect gas, the specific internal energy (erg/g) has no density dependence.
