Candidate epicyclic overdensities plotted in proper motions and tangential velocities together with the eDR3 final data selection. Top panel: tangential velocities, and bottom panel: proper motions. The underlying black points belong to model M5 at an age of 655 Myr. Open blue circles show the data after the S2 selection was applied based on model M5. The filled blue points are the final data after the S3 selection. In Fig. 13 two spatial overdensities are clearly visible (highlighted by semi-transparent vertical blue bars), and stars that belong to them are plotted as filled red circles (for the overdensity in the leading part of the tail) and as dark red circles (for the overdensity in the trailing part of the tail).
