Notes. The relative energy error of the simulation is estimated by 
with the absolute energy error 
.
fej, kin: unbound mass fraction of the envelope with kinetic energy exceeding gravitational binding energy, egrav + ekin > 0;
fej, therm: unbound mass fraction of the envelope with kinetic plus thermal energy, egrav + ekin + etherm > 0;
fej, OPAL: unbound mass fraction of the envelope with kinetic plus total internal energy (OPAL EoS only), egrav + ekin + eint > 0;
finorb: mass fraction of the envelope within the orbit of the two cores;
Eorb = (Mc + finorbMe)M2/(2a): orbital energy, not accounting for the mass outside of the orbit;
Etherm: thermal energy, determined from the EoS;
Erecomb: recombination energy for simulations employing the OPAL EoS only.
