Notes. Best fitting model parameters for each SN. Where appropriate, host galaxy extinction is included. The filters used to determine the best matching models are given. Explosion dates are given by the best matching model, while the uncertainty is calculated as the standard deviation of explosion dates from models within the 3σ range. Objects included in our gold sample are shown in bold. Within the group “consistent with ⁵⁶Ni distributions”, those SNe denoted with an asterisk represent objects for which we believe additional tuning of our models is necessary to produce improved agreement.
