Left: Difference between the centre of mass of the parent halo and the centre of mass of the bound subhalos calculated as the mass-weighted sum of all their centre-of-mass positions versus the number of bound subhalos. The difference in the centre-of-mass positions is scaled to the zero-velocity radius of the halo for comparison. Centre: Total angular momentum as given by Eq. (49) versus the number of bound subhalos. Right: Individual components of the angular momentum given by Eqs. (50)–(54) with respect to the total one versus the number of bound subhalos.
