Fourier amplitude spectrum of the binned BTr light curve of HD 201433. The two middle panels show the amplitude spectrum after pre-withening of the given frequencies. The bottom panel gives the residual amplitude spectrum after pre-withening with all significant frequenices. The right inset in the top panel shows the spectral window function of the BTr dataset. The left inset gives the original spectrum (black line) and the spectral window (red dashed line) centered on the main peak. The green and blue peaks indicate the posterior parameter distributions (arbitralily scaled in amplitude for better visibility) of a single and multiple sine fit with MultiNest, respectively.
