Stacked eROSITA surface brightness profile in the 0.2–2.3 keV band after the stray light component was removed. The radial distance to the cluster center is scaled to the overdensity radius r_200m. The corresponding physical radius given the sample median mass and redshift is labeled at the top of the figure. The top-right inset provides a zoomed-in view of the profile within a zoomed surface brightness range around the background level, with the dashed horizontal line indicating the average surface brightness between 3 and 4 r_200m. The profile shows significant X-ray emission extended to approximately 2 × r_200m.
