\caption{\label{tab1} A subset of the 3D~models performed. From left to
right, the columns give: class name; mean eccentricity; standard deviation of
inclination; mean mass; standard deviation of mass; lower-mass cutoff;
initial separations in mutual Hill radii; disc mass (normalised against
fiducial value); number of protoplanets.}
