OxQUB

Several matches with SNe Ia-CSM at 2-3 weeks post maximum light were obtained using SNID (e.g., SN2005gj at t = +18d). Redshift from SNID template matching, which matches that of the previous classification.

LiONS

The spectrum obtained by LJT is similar to the Ia-CMS/IIn event at the early phase (e.g. SN 2005gj at 12d after explosion via Gelato (Harutyunyan et al. 2008) or SN 2005gj at -12d before the peak via SNID (Blondin & Tonry 2007)).
