Bayesian-evidence comparison between different planetary configurations and stellar-activity kernels. Planetary configurations include a circular-orbit component (C_b; e = 0). For stellar activity, we utilised the MEP kernel and the ESP kernel with two, three, and four harmonics. The model that we elected for analysis assumed a planet-free model with a MEP kernel (red border; ln Z = -434.4). We give the Bayesian factor Δ ln Z of remaining models relative to this model.
