Notes. The explosion date, redshift, and extinction for SNe 2010jl, 2015da, 2017hcc, and 2021irp were taken from Fransson et al. (2014), Tartaglia et al. (2020), Moran et al. (2023), Reynolds et al. (2025a). The distance modulus for SN 2015da was estimated based on the luminosity distance of the host galaxy (53.2 Mpc; Karachentsev et al. 2017), while the distance moduli for the other SNe are derived from the adopted redshift.
