Contributions of some of the sinusoidal signals to the total flux around the transit phases. Top left: contributions of F2 around the individual transit events with blue symbols and shifted vertically from each other for a better view, overlaid on the folded transit curve. Bottom left: contribution of F2 after folding with the orbital period and binning, shown on a scale of 100 ppm. The right panels show the contributions of F2, F5, F6, and F10, as well as their sum.
