Best-fitting linked model results, with the 50th percentile value reported with the 16 and 84 percentiles as uncertainties. The fit without any spectroscopic temperature constraints is on the left and the fit with the constraint on |$T_\text{night}$| is on the right. For the independent parameters, the ordering of the results by data sets is as follows: LCO 2023, NOT 2023, and NOT 2024. Fitted parameters are reported at the top of the table and derived parameters in the middle. The mass ratio q reported is of the form |$M_{1}/M_{2}$|. Model reduced |$\chi ^2$| and band offsets are reported on the bottom third.
