Notes. The type Ic SNe in K13 are located in strongly star-forming galaxies. The results of other SN types in K13 are consistent with A12. The redshifts (radial velocities) of the host galaxies of the transients are obtained from these references if given, and from the NED if not, and converted to distances using H0 = 70 km s-1 Mpc-1, Ωm = 0.3, ΩΛ = 0.7.
