Coma cluster 5 × 5 deg image in the 0.4−2.3 keV band based on CPV data. Individual bright sources have been removed from the image. The resulting image (detector background subtracted and vignetting corrected) is smoothed with a σ = 60″ Gaussian. The two circles show the estimated positions of R_500c and R_200c. The excess emission at r ∼ R_500c in the SW direction is very clear. Indeed, in the majority of other directions, a similar level of X-rays surface brightness is more characteristic for r ≈ R_500c. Two arrows show the position of the 1253+275 radio source (its brightest part). A surface brightness edge is visible close to the position of the relic.
