Measured eROSITA gas fraction profiles with respect to the cosmic baryon fraction up to r_200m and the comparison with simulations. The observed profile from observation with and without residual clumpiness correction is plotted in the hatched and filled magenta bands, respectively. The bandwidth represents the uncertainty from halo concentration c_200c assumptions of from 3 to 5. The 1σ scatter of gas fraction profiles of M_500c > 10¹⁴ M_⊙ halos in the TNG300-1 simulations is plotted in a blue band, and the averaged gas fraction of halos with the selection function applied is plotted in the thick blue line.
