Notes. The table shows the assumed, adjusted, and fitted parameters with their priors and the derived parameters. The third column states whether the fitted parameter is used to model radial velocity (“RV”) and/or mid-transit and mid-occultation times (“Tr/Occ”. Error bars are reported with 1σ confidence level for all parameters, while for e, , and
, they are reported also with 2σ confidence level. For e, we also report the 5σ confidence level to strengthen the findings.(†) The stellar rotational period is fitted as in Equation (10) in Bernabò et al. (2024).
