Fig. 1


Suzaku XIS-0 + XIS-1 + XIS-3 mosaic image of A2744 in the 0.5–8 keV band. The image is corrected for exposure map and vignetting effects and is smoothed by a Gaussian function with σ = 24″. No background was subtracted. The X-ray peaks of the main cluster and the NW subcluster are marked with “+” and “x”, respectively. The spectral integration regions (0′−2′, 2′−5′, 5′−8′, 8′−12′) are shown with the white annuli, while point sources detected by XMM-Newton PN and MOS are eliminated with an r = 1′ radius (the cyan circles with red diagonal lines). The dashed white line denotes the virial radius . A fan-shaped r = 15′−18′ region in the south (green) was used to estimate background. The two corners of the CCD chip illuminated by 55Fe calibration sources are excluded from the image.
