How we define gain region: A zone is contained in the gain region if the matter energy source term from neutrinos $d\epsilon/dt>0$ .and. $\rho<3\times10^{10}$g/cm$^3$ .and. $s>6 k_\mathrm{B}/\mathrm{baryon}$. This eliminates zones at high density where spurious heating can occur, and zones outside the shock front where any energy exchange is minimal, but do not want to flag a zone as in the gain region.  How we define $E_\mathrm{gain}$: $\sum_i m_i [1/2 |v_i|^2 + \epsilon_i + \phi_i]$. Here $i$ loops over zones flagged as gain region (see above), $\epsilon_i$ is the internal energy (taking zero to be the natural zero of the Hempel SFHo EoS [note: ensure Hempel's zero makes sense for this; Hempel's zero is with AMU, so a gas of neutrons and protons will have a large (~8MeV/nuc) ($\sim$8MeV/nuc)  base internal energy... so still need to think here]), and $\phi_i$ is the gravitational potential of zone $i$.
