Fourier amplitude spectrum of the SMEI data set of HD 201433. The top panel gives the original spectrum (grey line) with the red and blue lines indicating the significant frequenices in the BTr data set (Table 2) and their mid-point, respectively. The inset shows the full frequency range. The middle panel shows the same spectrum along with a sequence of Lorentzian profiles (red line) fitted to the spectrum. The bottom panel shows the (color-coded) amplitude at the central frequencies of the Lorentzians as a function of time. The amplitudes are determined within a 720 d long subset moved across the full time series in 100 d steps. The horizontal dotted lines separate fully independent parts.
