Comparison of overdensities for Test D, for WF, LNP, ZADE, and cloning (from left to right), for the redshift bin 0.7 < z < 0.9 and tracers with M_B − log ₁₀(h) ≤ −19.4 − z. x-axis: overdensity in the reference catalogue (); y-axis, top panels: overdensity in the test catalogue (); y-axis, bottom panels: relative error (). The thick lines are the median value of the quantity displayed on the y-axis in each given x-axis bin. Thin lines represent the 16th and 84th percentiles of its distribution. Points are single cells, when cells per bin are <20 (in which case we do not compute a median and percentiles). Red and blue lines/symbols are for spheres with radius R₅ and R₈, respectively. See text for details about tests.
