Noise-filtering comparison of a simulated sinusoidal signal. The same number of template stars and LS parameters were used for TFA and TFAW. Top left: TFA-detrended and reconstructed phase folded signal. Red line corresponds to the simulated signal. Top right: same phase folded signal but TFAW-detrended, reconstructed and denoised. Bottom left: LS power spectrum of TFA frequency analysis step. Bottom right: LS power spectrum of TFAW frequency analysis step.
