Illustration of the detection of a super-Nyquist modulation in the orbital motion with Fourier analysis. Top panel: one quarter (90-d) long detail from a 600-d long simulation. Dots represent sampling by transits. Bottom panel: Fourier series of the 600 d long data set, extended beyond the Nyquist frequency. The actual frequency and the sub-Nyquist detections are highlighted. This specific model had an orbital (sampling) and modulation period of 11.21 and 4.76 days (which were taken from the ZIP code and altitude-above-sea-level of the Budapest station of Konkoly Observatory, as uncorrelated random numbers).
