Distributions of the reference (black line) and Test D overdensities (points) for the three redshift bins 0.5 < z < 0.7, 0.7 < z < 0.9, and 0.9 < z < 1.1 (from left to right), with tracers with M_B − log ₁₀(h) ≤ − 18.9 − z, M_B − log ₁₀(h) ≤ − 19.4 − z, and M_B − log ₁₀(h) ≤ − 19.9 − z, respectively. Top row is for cells with R = 5 h^-1 Mpc, bottom row for cells with R = 8 h^-1 Mpc. Different colours are for different methods, as specified in the label: WF (blue), LNP (green), ZADE (orange), cloning (red). Grey-shaded area is the rms around the black line, computed using the 26 light cones. To better appreciate the differences among the series of points, the 1 + δ_N distribution on the y-axis has been multiplied by the corresponding value of 1 + δ_N itself.
