ME plots in the (a − i) plane. The color code corresponds to the maximum eccentricity – red means low eccentricity and therefore stable motion, green and blue correspond to high eccentricities and therefore unstable motion (see color code). The plots are for different mass ratios and eccentricities of the gas giant: first column: μ = 0.0005, e₁ = 0,0.1,0.3 (up to down); second column: μ = 0.001, e₁ = 0,0.1,0.3 (up to down); third column: μ = 0.003, e₁ = 0,0.1,0.3 (up to down). The black dots indicate the orbits for which we also calculated LCI values (see Fig. 3).
