Time evolution of the resonant angles of the Agol et al. (2021) best fit. The left column shows the two-body resonant angles from Eqs. (2) to (12). The color scheme is as follows: blue is first angle θ⁽¹⁾, orange θ⁽²⁾, and if present, green and red θ⁽³⁾ and θ⁽⁴⁾, respectively. The middle and right columns show the three-body resonant angles from Eqs. (13) to (17). In the middle column they are plotted over the same 1600 days timescale as the two-body angles. On the right column they are plotted on a longer timeframe of 100 yr.
