Integrated Hα profiles for the 152 HRS galaxies concerning this work. The profiles are displayed over three times the free spectral range (∼25 Å top label, 1100 km s−1 bottom label). The calibrated intensity in erg seg−1 cm−2 nm−1 appears on the right side of the Y-axis. The black dashed vertical line represents the systemic velocity computed by the kinematical models; in the cases where a kinematical modeling was not possible, the corresponding systemic velocity taken from Boselli et al. (2010) is plotted instead.
