Initial (top) and final (bottom) distribution of test particles in our simulation. Green and red dots in the final distribution represent the positions from which the particles were ejected to hyperbolic orbits (red dots) and orbits with a > 100 au (green dots), whereas particles that survive whole simulation for 10 Myr are blue. Black lines represent the sets of (a, e) where a particle can be to have a perihelion (or aphelion) distance equal to the perihelion (or aphelion) distance of one of the planets. Planets are specified in the legend. For example, q_Jup represents the perihelion distance of Jupiter, Q_Jup the aphelion distance of Jupiter, etc. The orange line represents the perihelion distance of q = 0.26 au.
