Examples of some of our fits to the CHEOPS occultation data, showing a range of occultation depths. In each panel, the grey points represent the unbinned data with the pulsation signal subtracted, the larger, dark blue points are binned to 0.01 in orbital phase (about 17.6 minutes), and the green line is our best-fitting model for this particular treatment of the pulsations. A) three frequencies (from (Kálmán et al. 2022)) per occultation. B) 10 frequencies (from (von Essen et al. 2020)) fitted in common to all four occultations. C) as (B), but for 20 frequencies. D) 15 frequencies from this work (Section 4.2).
