Notes. The three methods are (a) assuming the average of the upper and lower limit of κ as effective opacity (mean κ; Könyves-Tóth et al. 2020); (b) assuming a fixed expansion velocity from the spectroscopic analysis (adopted υexp; Könyves-Tóth et al. 2020); and (c) performing a direct fit of the effective opacity (fitted κ; Nagy et al. 2014). The approximate uncertainties were computed from error propagation in the corresponding method. The only exception is MNi, where the Minim algorithm provided too low uncertainties from the fits; therefore, the uncertainty of the nickel masses was estimated as in Nagy & Vinkó (2016).
