Mass (upper panel) and eccentricity (lower panel) posteriors derived from our dynamical analysis of the TTVs. The corresponding values are given in Table D.1. In the upper panel, the RV prior based on the RV measurements presented in L21 is shown in black, with 1σ error bars. The coloured error bars show the median and .16–.84 quantiles confidence level of the mass posteriors obtained from our TTV fit using three different sets of priors.
