Notes. The metallicities for SNe 2010jl, 2015da, 2017hcc, 2021adxl, and 2022mma were derived from the value of 12 + log(O/H), adopting the solar value to be 12 + log(O/H)⊙ = 8.69 dex (Asplund et al. 2021). The host brightness was corrected for extinction. The metallicities for SNe 2010jl, 2015da, and 2021adxl were estimated for their local environments (local), while that for the others is for their host galaxies (global).
