Cylindrically averaged (2D) feed group pseudo-cross-spectra. Columns show, from left to right, the full spectra, the corresponding 1σ uncertainty, and the ratio between the two. Rows show, from top to bottom, Fields 1, 2, 3, and all three combined. The approximate angular scale, assuming the central COMAP redshift at z = 2.9, corresponding to each k_⊥ is shown as a twin axis on the upper row of plots. Thin green contours indicate the bin edges of the (1D) spherically averaged FGPXS.
