Orbital velocities for multiple primary and secondary masses (the lines correspond to different primaries). The velocity is calculated assuming the circularisation radius is reached before explosion. Two simulation values are plotted as circles. The black region shows min and max ejection velocities for D6-1,3, J1235, and J0927. Cyan and purple lines (and the corresponding shaded regions) show the values for J1637 and J0546, respectively, both matching slightly lower mass white dwarf secondaries.
