Comparison of continuum-subtracted and peak-normalised Hα profiles of SN 1994W-like events primarily around +35 d with a spectral resolution of R≥800. The Hα lines show similarly blueshifted P Cygni absorption minima around 600–700 km s⁻¹ (vertical dashed and solid lines, respectively). The spectral profile of SN 1999eb is contaminated by the host galaxy Hα line and the effect of the feature was estimated and excluded from the normalisation process.
