Weighted average of the WL mass bias of DEMNUni-Cov clusters with M_sim > M_min as a function of M_min. Results are compared with measurements performed on the Three Hundred cluster sample from ECG. Top panels give the fraction of clusters in the considered mass range (top) and the mass bias scatter (middle). The vertical line is at log M_min = 14.7 lower limit. Error bars are the standard deviation of the bootstrap sample distribution.
