Top panel: light curve of CoRoT 102918586 (a γ Doradus pulsator) with binary transits (at the top) and its local/global wavelet map (in the center/to the right). Bottom panel: light curve of CoRoT 102918586 with eclipses removed (at the top) and its local/global wavelet map (in the center/to the right). The main periodicities detected and illustrated in the GWS are P₁ = 0.82 d, corresponding to the nonradial fundamental pulsation period, P₂ = 18.61 d, related to the beat pattern, P₃ = 4.34 d and P₄ = 2.17 d, also related to the beat pattern (although they are not exactly equal to the harmonics of the P₂), and P₅ = 0.41 d, an overtone of P₁. Contour levels are 90%, 80%, 70%, ..., 20% and 10% of the map maximum. The 6th-order Morlet wavelet was used.
