Four Lomb-Scargle periodograms (upper: full frequency range; middle; zoomed version) of the γ Dor star KIC 11080103. The black and cyan curves stand for the Gaia DR3 G-band and Kepler light curves, respectively. The grey and blue periodograms result from prewhitening the Gaia G and Kepler data with the dominant frequency. The lower panel shows the Gaia DR3 G-band data (black squares) folded with the dominant frequency detected in common in both light curves; a harmonic fit with that frequency is overplotted (full blue line). For visibility purposes, the phase is shown for two cycles.
