Comparison of velocities from Hα in spectra of SNe 1993J, 1996al (considering the blue component of Hα), 2011fu (Kumar et al. 2013), 2011dh (Marion et al. 2014) 2018ivc (this work), and a sample of SNe IIP/IIL (Gutiérrez et al. 2017, using the minimum of the Hα absorption). For SN 2018ivc, the velocity is derived from the position of the minimum of the absorption.
