Spherically averaged FGPXS with 1σ uncertainties for Fields 1, 2 and 3 (orange, red and blue respectively) as well as the combination of the three (black) in units μK² Mpc² (upper panel) and in units of the 1σ power spectrum uncertainties (lower panel). The data points have been slightly offset from their true k-position to increase readability (see Table B.1 for an overview over bin centers, FGPXS values, and uncertainties).
