Spectral evolution of SN 1995ad. Wavelengths are in the observer’s rest frame. The phase reported for each spectrum is relative to the explosion date (JD 2 449 981), late spectra have been multiplied by a factor 5 and 60 to emphasise the features. The ⊕ symbol marks the positions of the most significant telluric absorptions. The second and third spectra are shifted upwards by 1 × 10-15; the other ones are shifted downwards with respect to the previous by 0.7 × 10-15 erg s-1 cm-2 Å-1.
