Periodogram of the radial velocity (upper panel) for each dataset individually (ESPRESSO in light green and HARPS in red) and for the joint dataset of both instruments assuming a 26 m s−1 offset (see Sect. 6). The activity indicators for the individual datasets are also shown in the lower panels. The periods of the three planets are marked as dotted vertical lines, and the rotation period (Prot = 131 days) and its first harmonic (Prot∕2 = 65 days) are marked as vertical dashed lines.
