Comparison of the right-hand sides of the inequalities – Eq. (25) (orange), Eq. (26) (green), and Eq. (27) (red) – as a function of α for γ = 1 and ε = 10⁻⁵ (upper three curves) or ε = 10⁻³ (lower three curves). The black curve is the critical AMD for the collision condition (Laskar & Petit 2017). The green and orange curves are on top of each other (see Fig. 3). The critical AMD from MMR overlap and circular criterion of Gladman (1993) are also plotted for comparison.
