Notes. MW extinctions are obtained via NED (Fitzpatrick 1999; Schlafly & Finkbeiner 2011). Redshifts are from NED except for PTF09gpn and PTF12kso, where we measured it from the narrow lines of their host-galaxy spectra. Distances are redshift-independent for the three CCCP SNe, and obtained from the redshift for the three PTF SNe (assuming WMAP5 cosmological parameters; Komatsu et al. 2009). PTF12kso is also known as SN 2012gg, CSS J043611.05-050452.1, and LSQ12fjm (Sternberg et al. 2012).
