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.
