Left: Best-fit results of the stacked 0.2–2.3 keV eROSITA surface brightness profile, where we adopted the gNFW model for the one-halo component. The width of each component denotes the 1σ scatter of the posterior samples. The inset shows a zoomed-in view around the background level. Right: Surface brightness profiles of the background-subtracted correlated signal (green) and the one-halo term signal. The systematic uncertainties of the uncorrelated background and the fitting uncertainties of the constant model and two-halo term normalization were propagated when calculating the profile uncertainty.
