Bayesian evidence comparison between different planetary configurations and stellar-activity kernels. Planetary configurations include circular orbit (C) and Keplerian (K) components. For stellar activity, we utilised the MEP kernel and the ESP kernel with 2, 3, and 4 harmonics. The model that we further elected for analysis assumed a model with a Keplerian signal, a circular signal, and an MEP kernel (red border; ln Z = −807.3). We give the Bayesian factor ∆ ln Z of remaining models relative to this model.
