Mass distribution of the clusters with λ ≥ 5, shown as probability distribution function (dashed blue line). The galaxy-selection criteria used here are the same as in Fig. 1. The dashed orange line represents the mass distribution of halos with log(M_200m/h⁻¹ M_⊙) ≥ 12.1 in the light cone. The green line indicates the weight applied to reconstruct the unbiased signal, scaled by a factor of 0.01 for visual comparison.
