Notes. The columns contain the following for each observed passband: the number of nights, the range between the last and the first observed nights, the number of data points, the mean time resolution of these points (δt), the Nyquist frequency (Nyq.), and the frequency resolution (δf) according to the Rayleigh criterion (1/ΔT).
