Left: profiles of apec normalization per area measured with XMM-Newton (blue solid) and Chandra (red solid). Red dashed lines indicate the best-fit 3D density profiles for an empirical density profile of Eq. (9) through a joint-fit of XMM-Newton and Chandra normalization profile. The corresponding normalization per area profiles derived with the best-fit 3D density profiles are shown in the cyan line, displaying good agreement with the measurements. Black dashed line is the deprojected density profile derived from Chandra surface brightness profile and the Chandra spectral analysis of the innermost bin. Right: projected temperature profile measured with XMM-Newton (blue solid line). The best-fit deprojected temperature profile is shown in cyan. The corresponding projected temperature profile derived from Eq. (16) is shown in yellow, in good consistent with the measurement.
