Proper motions of the orbit candidates. The blue dots represent the pairs of proper motions that match the position angle of CVn I, while the purple, red, green, and yellow dotted circles mark the zone of parameter space where the orbits have apogalactic distances of 245 kpc, 244 kpc, 243 kpc, and 242.5 kpc, respectively. The black crosses are the candidates for the final orbit (Table 2), while the red plus sign is the selected orbit.
