Neutrino luminosities as a function of postbounce time. In the left panels we show electron-type neutrino luminosities (solid lines show electron neutrinos while dashed-dotted lines show electron antineutrinos) and in the right panel we show the characteristic heavy-lepton neutrino luminosity (dashed line). For clarity, we show an inset to highlight the early accretion epoch for the electron-type neutrinos and a panel to show the neutronization burst. Some curves have been smoothed with neighboring zones to remove noise and improve clarity.
