Fig. 3
Epoch distribution of the SN Ia spectra observed at the NTT and the NOT, excluding the SNe with poor lightcurves. The un-filled histogram shows the full sample of SN Ia spectra, while the striped histogram shows the subset observed at the NOT. The epoch is defined as the number of days in rest frame since B-band maximum brightness, as obtained from the lightcurve. The 127 spectra are divided into epoch bins with a width of 3 days.
