Notes. The table gives the results of the explosion calculations with P-HOTB and presented in Ertl et al. (2020). In our work, the ⁵⁶Ni masses were taken from the Kepler approximation to the P-HOTB neutrino simulation. ⁵⁶Ni +“Tr”/2 is a realistic lower bound, ⁵⁶Ni +“Tr” is a reasonable upper bound, and 0.75× (⁵⁶Ni +“Tr”+α) is a generous upper bound. Our values (rightmost column) lie between the lower and generous upper bounds. Only the 4.0 M_⊙ He-star model is below the reasonable upper bound. Ertl et al. (2020) and Woosley et al. (2021) used the generous upper bounds for their light curve analysis, so our values are consistent with theirs.
