Posterior distribution of the GP hyperparameters for the 1.4-day signal in the TESS light curves from sector 4 (black), sector 31 with 2-minute cadence (orange), sector 31 with 20-second cadence (pink), and the combined light-curves dataset (blue). Priors are uniform between [−20,20] m.s⁻¹ for the logarithm of the amplitude, [0,10] days for the logarithm of the length, and [1,2] days for the period.
