Detгended light curve of CHEOPS visit 501. The colored regions correspond to the predicted transit time (with ±1σ errors) of planets d, f, 𝑔, and b according to the ephemerides from A22. The detrended CHEOPS data are represented by the light gray points, with their 5-min bins shown with the white dots. The black solid curve shows the fit of the four planet transits and arrows show the planets associated to each transit. Planet b is written in parentheses, as the depth of the event (~550 ppm) doesn't appear compatible with prior data (~250 ppm).
