Except for the inclinations, the remaining orbital parameters are free to vary for the (i_b,i_c) grid (50 × 50 fits). The solutions suggest a higher LOS inclination and close to coplanar configurations. There are no obvious stable solutions near the coplanar diagonal of best fits from i_b,c = 90° to 140°). Instead, there are many chaotic survivals and few stable islands at higher mutual inclinations, more than 3σ away from the grid minimum.
