Table 1: Parameters of the simulated collisions. M is the mass ratio (disturbed galaxy to disturbing galaxy), V the relative velocity at large distance (in km s^-1), and b the impact parameter (in kpc). The last column indicates whether, for simulations with a large DM halo truncation radius, massive TDGs were formed or not. In all these runs, orbital parameters are chosen to allow large tidal tails to develop. In particular the orbits of the galaxies were prograde.
