Notes.
The phase is given with respect to the light curve maximum, according to the light curve fitting.
The Galactic reddening towards the SNe targets has been estimated using the NASA/IPAC NED Galactic Extinction Calculator adopting the RV = 3.1 extinction law of Cardelli et al. (1989) and the extinction map given by Schlafly & Finkbeiner (2011). The host galaxy extinction was assumed to be negligible.
