Redshift evolution of the MGS observed in the Legacy Survey, measured in the North (orange dots) and South (white dots) regions. The observed MGS values are compared with those from the four redshift-calibrated Buzzard mock realizations before (purple lines) and then after sparseness correction, performed independently to match the North (green lines) and South (gray lines) regions. An almost complete match is observed between the observations and simulations, with only minor differences at z ∼ 0.4 and z > 0.8, where the mocks appear more sparse than the observations, making subsampling infeasible.
