The pseudobolometric light curve of SN 2022an (red) fit with the radioactive ⁵⁶Ni decay model obtained using the method outlined in N. Wygoda et al. (2019). The synthetic light curve of the SCH2p0 model (black) from S. Blondin et al. (2018) is shown for comparison. The three panels show the pseudobolometric luminosity (top), the time-weighted integrated luminosity (middle), and the ⁵⁶Ni-mass-independent quantity defined as the ratio of t^2.5L/∫Ltdt (bottom). The Phase 1 data for SN 2022an are shown with unfilled symbols.
