First-order wavelet coefficients (Eqs. (14) and (16)) for the fiducial light cone shown in Figure 1. Different colors correspond to different J modes, while solid (dashed) lines correspond to the case with (without) noise. Comparing the solid and dashed lines, we see that the signal is noise dominated at smaller scales (smaller J) and higher redshifts (see also Fig. 1).
