Caption: Figure 5.

Stokes I power spectra for the redshift range z = 9.6–10.6, before (top left) and after (top right) DD-calibration with SageCal-CO, respectively. Note the large drop in power of the foregrounds at low ﹩{k}_{\parallel }﹩ and the removal of substantial power above the wedge as well. The dashed slanted lines indicate, from bottom to top, the location of angular distances of 4.°5 and 10° from the phase center, and the maximum delay corresponding to the horizon as seen from the zenith. The ratio between these power spectra is shown in Figure 6.
