G1_G2 57 204 19.1 0.61 –38.0
G1_G3 52 183 16.8 0.59 –18.2

Notes. These parameters are obtained using E =  −2.85 × 104 km2 s-2 and tperi = 250 Myr. rini is the initial distance between the two galaxies, vini is the initial relative velocity of the two galaxies, rperi is the pericenter distance, e is the eccentricity of the orbits, and E is the orbital energy of the system.
