Semi-major axis vs. eccentricity diagram (left) and pole-on projection (right) of a disk of planetesimals after 2 Gyr under the influence of a one-solar-mass star of semi-major axis 2046  AU on an orbit of eccentricity 0.815. The disk is truncated at ~80 AU and nearly circular. It has no clear offset: its centre of symmetry is offset by ~6 AU from the star along the perturber major axis. With a disk mean semi-major axis of ~70 AU, this gives a global eccentricity of ~0.08.
