Example light curve and analysis results for the well sampled BVRIYJH bolometric light curve of SN 2004ex. The dashed-dotted, dashed, and dotted lines marks the ⁵⁶Ni decay, assuming an initial ⁵⁶Ni mass given by Arnett’s rule, the Khatami & Kasen (2019) method (dubbed “k&k”), and the lower limit from the Tail respectively. The fit used to obtain the maximum of the light curve is shown as a green dashed line.
