Column 2 lists the estimated explosion epoch, computed as the midpoint between the last non-detection and the discovery date. The host galaxy name is given in Column 3 (with “Anon.” indicating anonymous hosts), followed by the redshift (z in Col. 4) and the distance modulus (m-M in Col. 5; when not reported in the cited references, values are taken from the NASA/IPAC Extragalactic Database). Columns 6 and 7 report the total visual extinction, AV (Milky Way + host contribution, following Schlafly & Finkbeiner 2011), and the oxygen abundance at the SN site [12+log(O/H)], respectively. The final column lists the main references from which these quantities, as well as the multi-band photometric data and spectra used in this work, are collected. Entries marked as “NaN” indicate that the corresponding information is not available in the literature.

(a)

Unless otherwise specified in the cited references, the oxygen abundances are derived using the N2 diagnostic (see Taddia et al. 2013).

(b)

SN Refsdal, discovered in the MACS J1149+2223 galaxy cluster, was observed as a strongly lensed SN with multiple resolved images (Kelly et al. 2016). Among the four images, this work focuses on S2, assuming a magnification factor of μ = 15 (Grillo et al. 2016).

(c)

No public spectra are available for SN 2021zj during the secondary peak phase. Classified as a young SN II by Smith et al. (2021), it showed flash ionization signatures in the early spectra.
