Comparison in different halo mass bins between the PHOX input IGrM profiles convolved with the eROSITA PSF (green-shaded region) and the observed stacked profiles of Popesso et al. (2025, blue-shaded region). The latter profiles were obtained by following the same stacking procedure used here and with the real R11 GAMA optically selected group catalog. The shaded regions indicate the 1σ uncertainty.
