Notes. The peak absolute magnitudes and the colours at tpeak are k-corrected and corrected for MW extinction. The uncertainty on the time scales is of the order of a few days. The peak magnitudes and colours have a statistical error of ≈0.1 mag. The row “ZTF SLSNe” summarises the median values of the homogeneous ZTF SLSN sample (Chen et al. 2023b). Chen et al. (2023b) do not report the median rise and decline 1/e time-scale. We inferred that value from their median 1/10 rise time-scale and the relationship between the rise and decline time scales reported in that paper.
The redshifts of PS1-11ap and PS1-14bj are so high that the rest-frame g − r colour cannot be inferred from spectra published in Lunnan et al. (2014) and McCrum et al. (2014).
