Upper panel: residuals, with respect to the orbit computed from occultations, for the astrometry of (105) Artemis. Each symbol represents a single occultation event. Observations that are used for the final orbital fit are marked with stars. Crosses correspond to measurements that are automatically rejected. The circles show the nominal uncertainty (weight) of the occultations. Multi-chord events correspond to smaller circles. In the lower panel, the distribution of the occulted stars in ecliptic coordinates is shown.
