Heat map similar to that in S25 showing the comparison of Bayesian evidence (Δ ln Z) for different models. The x-axis displays different stellar-activity kernels in increasing order of complexity, while the y-axis shows different planetary configurations. Circular orbits (e= 0) are labelled ‘C’, while Keplerian orbits (e ≥ 0) are labelled ‘K’. The red rectangle highlights the best model based on the maximum Bayesian evidence.
