Resulting orbit for an initial circular orbit at R = 1.5 kpc, shown as R vs. φ in panel a), and as a polar plot in panel b). The net azimuthal and radial velocity components vs. φ are shown in panels c) and d), respectively. The dashed line in panel c) denotes v_c. Panels a) and b) show that the orbit is strongly distorted or lopsided spatially: it is shortened along φ = 0° and elongated in the opposite direction, i.e., along φ = 180°.
