Eight surface brightness profiles in the 0.3 − 2.0 keV energy band, one for each sector identified in Fig. 7. The other seven sectors for any given profile are plotted in gray for comparison, with the azimuthal average shown in black. The CXB measured to the northwest beyond 3r₂₀₀ is shown in navy blue. A selection of characteristic radii are shown as dash-dotted vertical brown lines. The scaled difference to the median is the difference between each sector and the median divided by the uncertainty (“in sigmas”).
