Please note: subsample 6 comprises only 2 clusters and the shown error based on the dispersion of the profiles has to be interpreted very cautiously.

The corresponding radii are shown in units of r₂₀₀ right to the figure. The error bars in the x-direction show the statistical uncertainty of the cluster temperature in each subsample (see text). The horizontal lines show the mean ScEM averaged over all the subsamples at the selected radii. The dotted line shows the relationship ${\it ScEM}\propto T$ and the dashed line ${\it ScEM} \propto T^{1.4}$ . Please note: subsample 6 comprises only 2 clusters and the shown error based on the dispersion of the profiles has to be interpreted cautiously.

The curve corresponding to $\alpha =4.3$ is our lower limit for the slope in the cluster outskirts (see text). This slope matches at the same time a density profile which follows the NFW-profile at these radii (see text). We normalize this $\alpha =4.3$ profile to match the data points at r=0.7 r₂₀₀.

The curve showing a power law with slope $\alpha =7.22$ is based on the fit in the outer parts of all ScEM profiles stacked together (see also Table 5). The symbols and error bars of the different subsamples are shifted with respect to each other only for visibility. The points of the different profiles have all the same location in x-direction.

$\begin{figure} \par\includegraphics[width=8.1cm,clip]{3015fig9.ps}\end{figure}$ Figure 9: Different density profiles in arbitrary units normalized to the same value at r=r₂₀₀. Since the NFW profile and the profile representing r^-2.65 have such an identical shape we choose a small offset between the two curves at r₂₀₀ to enhance the visibility of the plot. The line r^-2.65 represents the shallowest density profile, which is in agreement with our power law fits on the ScEM profiles in the external cluster parts. The curve with r^-4.11 represents the density distribution which originates from the best power law fit to the ScEM profile averaged over all clusters in the outer regions with ${\it ScEM}(r) \propto r^{-7.22}$ (see also Table 5).
