Fig. 4
Chandra data ([0.3–2] keV band) around the cluster main component (A), smoothed by a Gaussian with a width of 2.5 arcsec. The two red circles indicate the annulus (2.5′′−25′′) in which a possible 2.3σ extended contribution is detected; barred sources were masked in the analysis. Extending the search to 2.5′′−45′′ (cyan circle) decreases the significance to below 1σ.
