TLS periodograms of the detrended TESS light curve (see Sect. 2.1) showing peaks of the three transiting planets. The periodogram in the second panel was obtained after masking the transits of planet b, and that in the third panel was calculated after masking the transits of planets b and c. The dashed lines correspond to the harmonics of the orbital periods. Planets c and b were identified first in the ESPRESSO RV time series; their presence was confirmed by the transit signals detected in the TESS data.
