Evolutionary tracks of 100 synthetic D = 10 km asteroids started near the J3/1 resonance in the zone of Eulalia family. Their mean orbital elements were computed in a 5 Myr wide running window with 0.25 Myr shift: mean a vs. mean e (top), mean a vs. mean sinI (bottom). The simulation covered roughly 1 Gyr interval of time until the particles were eliminated from the simulation. Test bodies were given Yarkovsky drift-rate corresponding to the body of the chosen size and an effective obliquity ≃60° (Sect. 3.1). Initial orbits are highlighted by the upper and left box (the arrow recalls sense of migration in a). The bottom and right box shows current location of 495 Eulalia and its close clones (see the main text).
