Surface brightness profiles (PIB-subtracted) for the eastern and western clusters (left and right panels, respectively) in the 0.5 − 2 keV band. The total (cluster+CXB) PSF-convolved profiles are displayed in black, while the cluster-only PSF-deconvolved profiles are shown in the filled blue band, which represents the 68.3% error band. The R₅₀₀ and R₂₀₀ values are displayed with the dashed green and blue vertical lines respectively. The CXB level is displayed with the black horizontal line.
