Cleaned, background-subtracted, and smoothed count rate mosaic images in the 0.5−2 keV band from XMM-Newton and the entire A3532/30-A3528 system (left) and from Suzaku and the filament region alone (right). Left: R₅₀₀ and R₂₀₀ radii of all clusters are shown with solid white and dashed cyan circles respectively. The yellow boxes correspond to the sky areas of the four Suzaku pointings. The dashed white boxes show the regions from which we extracted and fit the Suzaku spectra to obtain the thermal properties of the filament. The BG-X1 and BG-X2 pointings show the pointings from which we extracted the CXB count rate and spectra using XMM-Newton. The point sources in the mosaic image are left unmasked for visual purposes. Right: regions we studied for the axial surface brightness profile (seven dashed white boxes) and for the radial surface brightness profile (four yellow solid boxes). The applied masks correspond to 1′ and 2′ masks for faint and bright AGN respectively, and to the R₂₀₀ of the surrounding clusters.
