Observed minus calculated synthetic diagrams derived from the joint RV and TTV dynamical analysis with TRADES for planet b (left panel) and c (right panel). The O – C for the best-fit (MAP) model is plotted with a black line, while the observed data points are the orange circles. The shaded grey regions displays the confidence intervals at 1, 2, and 3σ, as inferred from the 200 samples randomly drawn from the merged posterior distributions. Residuals are shown in the lower panels.
