2DPS of the fiducial model shown in Fig. 1. Different columns show the 2DPS for the pure cosmic signal and including thermal noise, as labeled on the top. Each pair corresponds to a different central redshift, coinciding with those used in the 1DPS summary (see Fig. 2). Furthermore, the bins between 1DPS and 2DPS coincide as much as possible. As in the 1DPS case, high-k modes and high redshifts are noise dominated.
