GLS periodograms of the data from the VIS channel (a) and (b), the NIR channel (c) and (d), and ESPRESSO (e) and (f). Bottom panels always show the residual periodograms after subtracting the 2.3 d signal. The 2.3 d and the 134 d signal are indicated by the vertical orange dotted and vertical red dashed line, respectively. FAPs are indicated by horizontal lines: 10 (dash-dotted red), 1 (dotted green), 0.1% (dashed blue).
