GLS periodograms for TESS light (black line) and CARMENES VIS (blue lines) data set analysis of the photometric and spectroscopic data. In the sixth panel (from top to bottom), the Ca II IRT is plotted in light (1), medium (2), and dark (3) colours. The stellar rotation period and its first harmonic are shown as two vertical yellow bands centred at 0.196 d⁻¹ (5.1 d) and 0.392 d⁻¹ (2.6 d). The vertical purple line indicates the orbital period of the transiting planet. The horizontal dashed blue lines correspond to the FAP levels of 0.1%, 1%, and 10%. However, the TESS panel only includes the 0.1% FAP multiplied by a factor of 10 for clarity.
