Notes. For systems in which the unconstrained Keplerian model was statistically indistinguishable from the no-planet model (Δ ln Z ≤ 2) or resulted in unsatisfactory convergence, we applied an informed model (or models). In the multi-planet systems TOI-2295 and TOI-2537, an unconstrained one-Keplerian model was applied to the outer planet. The star TOI-4168 is excluded from the table due to bimodality in the posterior distribution of its no-planet model (see Sect. 4.4). (1)The model resulted in unsatisfactory convergence. (2)Gaussian priors were applied to Tc and period based on TESS photometry.
