Maxima of all ejection velocity spectra as given in Fig. 8 with respect to terminal accretor mass (M_WD, f), where v_max indicates the absolute maximum and v_max(M_d) the maximum, with respect to the center of mass of the progenitor binary, for a given mass of the ejected companion (M_d). Black lines indicate inferred ejection velocities as calculated by Geier et al. (2015) and using proper motions as provided by Gaia DR2 (Gaia Collaboration 2018). The dashed lines indicate the expected continuation of the maxima towards areas of the parameter space insufficiently covered by the grid.
