ZelmaniLeak: Our neutrino leakage scheme that computes a gray optical depth estimate along radial rays for electron neutrinos, electron antineutrinos, and heavy-lepton neutrinos (nux), and then computes local energy and lepton number loss terms. Optionally, energy can be deposited based on a luminosity, flux factor, and mean energy estimate for electron and electron antineutrinos. Details can be found in Ott et al. 2012, Ott et al. 2013, and O’Connor & Ott 2010. Please cite O’Connor & Ott 2010 and Ott et al. 2012 if you use ZelmaniLeak or derivatives of it.
