Posterior densities for the GP model hyperparameters estimated from the ground-based LCOGT observations and from separate TESS sectors. First column: GP coherence scale. Second column: GP harmonic complexity. Third column: amplitude of the periodicity. The 11.4 h period is estimated only from the TESS Sectors 9 and 36. The ground-based posterior estimates for the 25.01 h and 23.1 min periodicities are significantly better than the TESS ones due to the significantly higher photometric precision.
