0.5–3 keV background-subtracted azimuthally averaged surface brightness profile of the outskirts of Abell 133 obtained from Chandra (black) and Suzaku (grey) data with the corresponding best-fit power-law models overplotted. The Suzaku sky background level is relatively higher compared to Chandra, which reflects the excess emission from Chandra-selected point sources whose PSF is broader than the source extraction region.
