Measured metallicity in profiles running north to south along the metal-rich filament (upper panel) and east to west across the filament. The black dots refer to XMM-Newton metal-abundance values, while the red triangles refer to the Chandra values. The XMM-Newton of the fit in the corresponding box is plotted below each panel. The blue lines represent where the filament is located relative to the boxes. The numbers on the x-axis are the numbers of the boxes in Fig. 4.
