Notes. All host-galaxy data were obtained from the NASA Extragalactic Database (NED), where vh is the measured heliocentric recession velocity and the Milky Way extinctions are from the Schlafly & Finkbeiner (2011) calibration of the Schlegel et al. (1998) infrared-based dust maps. The host-galaxy comoving distances have been calculated based on the redshift with H0 = 73 ± 5 km s-1 Mpc-1. The projected distances from the host-galaxy nuclei, r, were calculated based on the host-galaxy distances and the SN offsets.
