Notes. The works included in the table all discuss photometric properties of SNe IIn. For the sample size counts, the SNe labelled as SNe IIn by the respective authors were used. If available, the redshifts (z) of the SNe in each sample were taken from the respective papers. Otherwise, distance moduli or luminosity distances given in the papers were converted to redshifts using cosmological parameters from Sect. 3 without infall correction. Li et al. (2002) gives no distance information for their sample SNe; here, NED redshifts for their respective SN host galaxies were used.
