\caption{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.}
