HE sparsity bias b_s200, 500 and b_s200, 2500 as function of M₂₀₀ (top panels) and b_s500, 2500 as function of M₅₀₀ (bottom panel) for the X (left panels) and SZ (right panels) masses of the full cluster sample at z = 0.0 (blue circles), 0.5 (magenta squares), and 1.0 (green stars). The different lines correspond to the median (solid) and the mean (dashed), while the shaded area to the region comprised between the 16th and 84th percentile.
