Phase plot of the strongest pulsation. The light curves of the three TESS epochs in 2019, 2022, and 2024 were folded with 57 times the pulsation period P_puls = 0.17286 d and binned, i.e., averaged. The fold period P_fold = 9.853528 d is close to twice the orbital period, but not exactly equal to it. This brings the eclipses somewhat out of phase, but it is accurate enough to bin the orbital cycle and keeps the intervals of the phased and binned pulsation light curves. The lower panel shows a portion of the phased and binned light curves of the upper panel.
