Dynamical occupancy maps in the a - e plane for G1 (left panel), G2 (middle panel) and G3 (right panel). Colours indicate the fraction of total integration time spent in each of the 1000 grid cells. Solid black curves mark perihelion q = 1.3 au and aphelion Q = 2.06 au. Dashed vertical lines denote the group boundaries at a = 2.06 au and a = 2.5 au.
