Notes. ^(a) Initial distance between the two galaxies, in kpc.
^(b) Absolute value of the initial relative velocity, in units of 100 km s^-1.
^(c) $L=\mid\vec{r}_{\rm ini} \times \vec{v}_{\rm ini}\mid$ , in units of 10² km s^-1 kpc.
^(d) $E={v_{\rm ini}}^2/2-G(m_1+m_2)/r_{\rm ini}$ , with $m_1=2.3\times10^{11}~M_{\odot}$ and $m_2=2.3\times10^{10}~M_{\odot}$ , in units of 10⁴ km² s^-2.
^(e) Orbital spin, if parallel (up) or antiparallel (down) to the z-axis.
