Results from the P₂∕P₁ vs. P₁ grid constructed from coplanar edge-on dynamical fits. The separate panels are self-explanatory: Top-left panel: grid surfaces, where the red contours denote the 1σ, 2σ, and 3σ levels from the grid’s best fit. The best fit itself is found near the 6:1 period ratio and is marked with a black star symbol in all panels. The RV rms contour levels show consistency with the surface, with lower rms values found around the best fit. Other panels: all the 6:1 MMR resonance angles (the secular Δω and θ₁ –θ₆), and their libration semi-amplitudes on the grid. The red ⊙ symbol marks the minimum libration amplitude for each resonant angle. These plots show that almost all fits within the formal 3σ confidence level exhibit resonance behavior with all six 6:1 MMR angles librating. See text for details.
