Parametrization of the phase-folded, binned test signals by DSP (see Eq. B.1). Several realizations of the signal described in the text and in the caption of Fig. B.2 were used with injected box depth of δ = 0.15 ppt. The width of the bins is equal to the eclipse duration of WASP-5, and are distributed according to the eclipse phase (centered arbitrarily at phase zero). In both cases, one realization is shown by a black line to follow bin-by-bin fluctuations more easily. To avoid unnecessary jamming, we show only realizations with the largest negative bin average at the eclipse center. The difference in the overall eclipse depth in the two cases is due to the different DSP cutoffs used.
