a) Projected orbit of the cluster on the xy-plane, which is close to the cluster’s orbital plane, is illustrated. The symbols on the orbit mark the apsides of the 3D orbit. Each symbol/color corresponds to a particular age. The thick symbols mark the exact position of the apsides, while the thin symbols refer to the closest available snapshot of the simulated cluster by considering the time resolution of the simulations. b) Projected snapshots of the cluster on the xy-plane are shown at apocenters and pericenters. Each snapshot corresponds to one marked apside on the projected orbit. The sources are colored based on the present velocity variation in the cluster and its tidal tails.
