Comparison between SN 2023ixf (brown), SN 2013by (blue), SN 2013ej (green), SN 2014G (red), and SN 2024bch (gold) light curves. We only show the filters for which data are available for all the aforementioned supernovae: (top row) m2, w1, w2; (middle row) U, B, V; (bottom row) g, r, i. The SN 2023ixf data points are interpolated with GPs. The SN 2023ixf observation in the V-band at ∼800 days post-explosion is not used for comparison. The red line is the GP regression model for the SN data in the selected band.
