Magnitude at the Event B peak as a function of the magnitude at the Event A peak. Measurements were performed in the r and R bands when available. For SNe not covered during Event A in r (SNe 2025csc, 2022ytx, and 2019mry), we performed the measurements in the orange band for SNe 2025csc and 2022ytx, and in the I band for SN 2019mry. Colours are the same as in Fig. 13. Error bars are present but often smaller than the data points.
