Normalised histograms of the sparsity s_200, 500 (left panels), s_200, 2500 (central panels), and s_500, 2500 (right panels) obtained from the analysis of the MDPL2 sub-sample (dark blue bars) and The300/DM-only catalogue (goldenrod filled bars) at z = 0.0 (top panels), 0.5 (middle panels), and 1.0 (bottom panels), where the MDPL2 sub-sample consists of haloes with a mass larger than the minimum mass of the DM-only catalogue at the redshift considered. The vertical lines in each panel correspond to the median sparsities for the MDPL2 sub-sample (dark blue dotted line) and the The300/DM-only sample (goldenrod solid line).
