Fig. 11


Spectral comparison of PTF12os (blue), iPTF13bvn (red), and SN 2011dh (gray). The spectra have been normalized using the median and shifted by a constant for each epoch. The thick dashed lines show the rest wavelength of Hα, Hβ, and Hγ, and the thin dashed lines mark the corresponding wavelengths shifted by 14 000 km s-1, which coincides very well with absorption minima in the spectra of PTF12os for all three lines. The spectra have been smoothed to improve their visibility. The date labels refer to the date of the spectral observations of PTF12os for each epoch. The spectra of the other SNe have been chosen as close as possible to these epochs.
