Left panel: average strength of the total specific orbital angular momentum of the system of satellites contained within a sphere of radius R_max centred on their central galaxy. Middle panel: evolution of the ratio between the component of the satellite orbital momentum aligned with the spin of the central galaxy over the norm of the total satellite orbital angular momentum. Right panel: evolution of the dispersion of orbital angular momentum σ_plane over the norm of the total satellite orbital angular momentum for systems of satellites enclosed in spheres of increasing radius around the central galaxy. The specific orbital angular momentum of satellites decreases for satellites closer to the central galaxy, and the relative importance of the aligned angular momentum component increases for satellites closer to the central galaxy, while the relative amplitude of the dispersion between satellite orbits decreases.
