Raw (top), filtered (middle), and residual (bottom) RVs of AU Mic (red dots) over the observing period. The top panel shows the MCMC fit to the data, including a QP GPR modeling of the activity and the RV signatures of all four planets (cyan). The middle panel shows the planet RV signatures (pink, blue, green, orange, and cyan for planets b, c, d, e, and b+c+d+e, respectively) once activity is filtered out. The rms of the residuals is 10.1 m s⁻¹. A zoom on the 2023 and 2024 data is shown in Fig. D.1.
