Fig. 2


Comparison of Hβ and Fe ii λ5169 velocities. The coloured points correspond to velocities measured between 5 and 40 days from explosion, while the gray points represent epochs either within 5 days of the explosion or after 40 days. The solid lines correspond to the fitted evolution of the Hβ and Fe ii λ5169 velocities for each SN. The green and yellow shaded regions reflect the vH β /vFe 5169 ratios as presented by Nugent et al. (2006) and Poznanski et al. (2010).
