Fig. 8 continued. Models of the soft X-ray surface brightness profiles for the stellar mass-selected sample with mass M^* > 1.7 × 10¹⁰ M_⊙ (top left, 10.25), M^* > 3.1 × 10¹⁰ M_⊙ (top right, 10.5), M^* > 5.6 × 10¹⁰ M_⊙ (bottom left, 10.75), M^* > 10¹¹ M_⊙ (bottom right, 11.0). The model accounts well for the measurements. The point source, satellite and two-halo terms show little evolution. The hot gas model brightness increases significantly with the stellar mass threshold.
