Fig. 3


XMM-Newton and Chandra observations of MACS J0717.5+3745. Top left panel: exposure- and vignetting-corrected Chandra photon count image in the [0.5−2.5] keV band. The image has a resolution of 3.1′′. Top right image: wavelet de-noised map of the Chandra image shown in the top left panel. Iso-contours are shown with black solid lines to enhance substructures. The four regions in Table 2 are highlighted with black circles. Bottom left image: XMM-Newton wavelet de-noised temperature map, obtained using a threshold cut of 1σ. Contours from the wavelet map image are overlaid using white contours. Bottom right image: same as bottom left panel except that we show the temperature map computed using the Chandra dataset. All the maps shown are centered on the X-ray peak.
