For each panel, top: deprojected scaled density profile obtained using Chandra and XMM-Newton plotted using black solid line and blue points, respectively. We also show the parametric density profiles published in V06 with red crosses. For each panel, bottom: ratio between the Chandra and the XMM-Newton density profiles and between our Chandra and V06/V09 samples using blue and red shaded areas, respectively. The solid line and the dotted lines represent the unity and the ± 5% levels, respectively.
