P(k) over Band 2 (left) and Band 1 (right) with a colour scale that highlights cells with positive or negative values. We expect regions that are thermal noise dominated to contain an equal number of positive and negative estimates and regions that are dominated by foreground leakage to be entirely positive. We observe significant foreground contamination outside of the wedge up to |$k_\Vert \approx 0.5$| h Mpc⁻¹ in both bands.
