Light curve comparison between the SN observations (gray markers; Chen et al. 2024 bolometric) and the bolometric output from our double-peaked ⁵⁶Ni distribution model. The inner component of the distribution is varied, while a fixed outer component of the profile is set to provide a reasonable fit for the first maximum of the LC. The model including a magnetar component is shown in magenta. In all the cases, the external enriched ⁵⁶Ni shell is fixed, and the progenitor is the He11, as detailed in the text.
