Fig. 4
Observed spectrum of SN 2012gs obtained with FORS2 on MJD 56 252.0 (black line) is compared to that of the SN Ic 2007gr at phase −9d (top) and of the type Ia SN 1991T at phase + 14d (bottom). In both cases it is adopted for SN 2012gs at redshift z = 0.5, as measured from the narrow emission lines of the host galaxy.
