1DPS for the fiducial light cone shown in Figure 1. Different colors correspond to different wave modes, while solid (dashed) lines correspond to light cones with (without) noise. Comparing the solid and dashed lines, we see that the signal is noise dominated at higher k modes and redshifts (see also Fig. 1). All power spectra are computed from comoving cubes extracted from the light cone, centered on the redshifts indicated by the vertical dashed lines.
