Summary of the periodogram analysis of the independent ESPRESSO and CARMENES datasets. Top panels: raw RVs with the best fit activity model (red line) for ESPRESSO (left) and CARMENES (right), and their respective periodograms. The shaded red region highlights the period interval of the measured stellar rotation. Middle panels: RVs, after subtracting the activity model, with the best fit planetary model (red line) for ESPRESSO (left) and CARMENES (right), and their respective periodograms. The shaded green lines highlight the position of the planetary signals identified in the combined analysis. Bottom panels: residual RVs after the best fit (red line) for ESPRESSO (left) and CARMENES (right), and their respective periodograms.
