The FFT data are computed from the time evolution of the r-component of three velocity fields at the spatial point (r, θ) ≃ (re/2, π/2). The parabolic interpolations of the prominent peaks are shown as an example. The FFT spectrum at a single spatial point usually shows peaks that are sharp enough for analysis.
