Notes. We assumed the metallicity gradients measured by P04 for the hosts of eight SN IMs, and we checked them against our measurements, when available (see Fig. 7). In the last column, “SN" indicates that the SN is still bright in the optical. All the NCR values are from H14. For SNe 2002kg and 2003gm there are also metallicity measurements by Maund et al. (2006), which are consistent with our results.
The metallicity gradient is assumed to be −0.47 , from the average of the metallicity gradients presented by P04.
Metallicity from the N2 limit obtained from the spectrum of the closest H ii region, as the gradient of the galaxy is difficult to obtain given that the host of SN 2005-OT is strongly titled and irregular.
Metallicity obtained from the spectrum of the closest H ii region, as the gradient of this large galaxy is difficult to obtain given that the host of V1 is larger than the ALFOSC field of view.
Metallicity from the spectrum of the closest H ii region as measured in S12, as we could not determine the emission line fluxes from our NOT spectra, where the SN is still detected.
Metallicity from the spectrum of the closest H ii region, see Tartaglia et al. 2015.
Metallicity from the spectrum of the closest H ii region, as SN 1995N sits in a irregular galaxy whose gradient is difficult to determine.
N2 metallicities obtained from O3N2 values converted to the N2 scale using the relation in Kewley & Ellison (2008).
