Notes. Orbital elements are in the Jacobi frame and are valid for the first HIRES observational epoch BJD = 2 451 581.046. The dynamical modeling of the combined HIRES and CARMENES data was unable to constrain the mutual inclination. (a) –
diffrence between the best-fit two-planet model and the Null model (no planets).
