Positions of the shock fronts in A2163 (blue), the X-ray emission peak (black diamond), and the approximate position of the cool core (magenta ellipse) found by Bourdin et al. (2011). The widths of the shock positions correspond to the uncertainties on the jump radius, estimated from the deprojection (see Table 2). Green contours show the extended radio emission with the same contour levels as in the right panel of Fig. 2. The yellow letter “R” marks the position of the radio relic as identified in Feretti et al. (2001).
