Planet b and c eccentricity, as well as the mutual inclination for the different analysis presented in this work, and in previous literature. Maciejewski et al. (2020) used a t_ref = 2 459 048.747 BJD_tdb, which is different from the one used in this work, but the difference in the inferred orbital parameters cannot be explained by their evolution between the two epochs (Fig. A.6). We adopted the values labelled as ‘stable’.
