Stability analysis based on the MEGNO parameter for different scenarios for the two-planetconfiguration. We explored 1000 different values of the orbital inclination ranging from 90° to 10°, for three different sets of eccentricities corresponding to their nominal values ±1σ uncertainties: (1) the solid-green line corresponding to e_b = 0.03 and e_c = 0.05; (2) the solid-yellow line, which corresponds to e_b = 0.10 and e_c = 0.17; and (3) the solid-red line for e_b = 0.19 and e_c = 0.30. For clarity, scenarios (1) and (2) have been shifted by 0.5 units from ⟨Y (t)⟩ = 2. On the x-axis, for each inclination the corresponding planetary mass is shown due to the mass-inclination degeneracy.
