Example of 0.7–7 keV spectra and the best-fit models of the first annulus outside r₂₀₀ (82′< r < 85′) in the NW arm. The best-fit NXB models have been subtracted. Data from all three detectors are shown - XIS0 (blue), XIS1 (yellow) and XIS3 (green). The CXFB models are marked with dotted lines and ICM models are denoted with dashed lines. The data has been rebinned to S/N≥3 for illustration purpose, while the fit was performed on the data binned with a minimum of one count. The lower two panels show the fitting residuals including and excluding the ICM component respectively.
