TRADES modelling of AU Mic b (left panels) and AU Mic c (right panels) of configuration (1). Top panel: (O – C) diagram, observed T₀s are plotted with coloured markers with black stroke (different colour and marker for each telescope), while the simulated O – C values computed by the best-fit TRADE S dynamical model are plotted as black line with black circles (corresponding to the observations). Grey-shaded areas correspond to 1, 2, and 3σ of random samples drawn from the posterior distribution of TRADES. Bottom panel: Residuals computed as the difference between observed and simulated T₀s.
