Scatter in the group stellar mass distribution as a function of halo mass, measured from cosmological simulations. The shaded region indicates the 68% credible interval of the constant scatter constrained by our baseline model (Table 3). The solid and dashed lines represent the scatter model from Eq. (26) with Aσ set to 0.1 and 0.1 ± 0.05, respectively.
