Top panel: doppler velocity at maximum absorption in Fe II 5169 Å for our set of models. We also overplot our measurements for Type II-pec SNe 1987A, 2000cb, 2006V, 2006au, and 2009E. Middle panel: same as top, but now for Hα. A gaussian smoothing with a width of 10–20 Å is used for noisy spectra or when the Hα suffers from strong overlap (e.g., for SN 2006au). In the latter case, the measurement is merely indicative. Bottom panel: montage of spectra for our set of models showing the Hα line profile in Doppler-velocity space at about 200 d after explosion.
