Notes. ^(a)Mean value of E(B − V) from Schlafly & Finkbeiner (2011).

^(b)Details of the host extinction estimate are described Sect. 3.3. If the value of E(B − V)_host is reported, this corresponds to the 50th percentile (median) of its marginalized distribution from the MCMC routine described in the aforementioned section. The lower and upper uncertainties correspond to the 50th–16th and 84th–50th percentiles of such marginalized distribution, respectively.

^(c)Boolean column representing if the SN was observed in X-ray.

^(d)Boolean column representing if the SN has been modeled using MOSFiT.

^(f)The extinction in R/r-like bands was estimated directly from the posterior samples of E(B − V)_host instead of the value tabulated here. Reported values SN 2018jmt, SN 2022ablq and SN 2023emq are retrieved from the respective references.
