Epochs covered by existing data with CHEOPS, JWST, and HST WFC3 UVIS, as well as those that will be covered in TESS Sector 69. Overplotted are our best-fit models when the Spitzer transit timings are included in the analysis. With these data, the apsidal precession model is likely to be conclusively ruled out while the decay model will still be harder to distinguish from the linear period, although stronger constraints on the maximum decay rate could be placed.
