Distributions of reference overdensities for the spheres falling in the first, third and fifth quintiles of the density distribution computed in Test D, using ZADE. Left, middle and right panels are for the three redshift bins 0.5 < z < 0.7, 0.7 < z < 0.9 and 0.9 < z < 1.1, 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. Shades of red (top) are for cells with R = 5 h^-1 Mpc, while shades of blue (bottom) are for cells with R = 8 h^-1 Mpc. For both radii, colours from light to dark are for the first, third and fifth quintiles of the Test D density distribution. Bins on the x-axis are different in all panels (for smoothing purposes), so normalisation is not comparable among panels. All distributions are normalised to unity. Results obtained with the LNP method are very similar. See also Table 2.
