Static parent body. Modeling results in the case of a static parent body. Top left: map of the reduced χ² () obtained by fitting the position of the five structures. The solid and dashed black lines show the expected power law trends (Eq. (9)) along the two families of solutions, each scaled to go through the best fits identified by the black crosses. The branch of highest R₀ values corresponds to trajectories going away from the observer, while the other branch identifies the solutions pointing to the observer (see also Fig. A.1). The area under the dotted white line are solutions excluded by Eq. (7). Bottom left: map of the angle of emission, taken with respect to the observer. Top right: projected positions as a function of time. The solid lines correspond to trajectories going away from the observer, while the dashed lines are trajectories pointing toward the observer (see also deprojected trajectories seen from above in Fig. A.1). Bottom right: same as Fig. 2, overlaid with the best fit solutions (black crosses in top left panel).
