Residual X-ray emission of SPT0615. Top left: Chandra image of SPT0615 used for the 2D fitting with a beta model. We also indicate the angular region we used to measure the surface brightness profile in Fig. 10. Top right: beta model and best-fit parameters. Bottom: residual from the fit. The region near the hot core is very clearly detached from the other excess over the beta-model fit region. A larger excess region over a significant part of the central cluster elongation is visible as well. It extends 280 kpc to each side from the center. North is up, and east is left.
