ent[input, unit: $c^2$] log-enthalpy H defined by $H = c^2 \ln\left( {e+p \over m_B c^2 n} \right) $, where e is the (total) energy density, p the pressure, n the baryon density, and $m_B$ the baryon mass
parpossible extra parameters of the EOS
Returns
baryon density [unit: $n_{\rm nuc} := 0.1 \ {\rm fm}^{-3}$]
