Bolometric LC data for each SN in our sample. The name of each SN is indicated within its panel. The adopted explosion epochs (t = 0) are fixed from observational constraints (see Table 2). Along with the data, we present the synthetic LCs obtained from the analytical model described in Paper II. The parameters for these models were determined using the prior values given by the scaling relations, and the best-fit model obtained from SUPERBAM analysis. The shaded region marks the LCs associated with the explored parameters within the error ranges of the MC method. Data earlier than 30 days are not included in the fitting procedure. For comparison, the synthetic LC of the nickel-free model by Popov (1993) is also included, calculated for the best-model parameters.
