Projected, PSF-corrected emission measure profile of A2163 obtained from the spectral fit for the NE (solid red diamonds) and SW (dashed blue diamonds) directions. Dashed and dotted lines have the same meaning as in Fig. 3. The innermost annulus is not shown as it is not considered in the deprojection procedure (see text). The profiles reproduced from the deprojection models (dotted lines) well match the measured profiles.
