Generalized Lomb-Scargle periodogram of: the HARPS TERRA RV measurements (first panel); the RV residuals following the subtraction of the Doppler signal of HD 190622c (second panel); the RV residuals following the subtraction of the Doppler signals of HD 190622b and c (third panel); the FWHM and BIS of the CCF (fourth and fifth panels); and the CaIIH&K line activity indicator log . The vertical lines mark the orbital frequencies of HD 190622b and c, while the horizontal lines show the FAP at 0.1%.
