Growth curve analysis for the unabsorbed, background subtracted 0.5 − 2 keV X-ray flux as a function of projected cluster radius. The blue solid line shows the total 0.5 − 2 keV flux inside the projected radius r as measured with the XMM-Newton PN camera, the red line represents the sum of the two MOS instruments. Poisson errors plus 5% uncertainties in the background determination are displayed by the dashed lines, the vertical line depicts the R₅₀₀ radius. The fully consistent Chandra GCA result is overplotted in black. The X-ray emission can be traced out to about 90″, where it reaches the plateau value.
