Notes. The names of the hydrodynamic models are given in the left column. and are the initial 56Ni masses computed at the onset of light curve modeling and , respectively (see Table 2). The other columns provide the 56Ni mass ejected at day 150, Mf, the fallback mass of 56Ni, δMNi, during the period from tmap to day 150, and the total fallback mass, δMtot, during the same period; all values for the early- and late-time 1D simulations. Note that Mf = MiδMNi.
