Comparison between the SLN and Γ_e methods at 0.9 <z< 1.1. Each panel corresponds to a cell radius R of 4, 6, and 8 h^-1 Mpc from left to right. Top: the red histogram shows the observed PDF in the MOCK catalogues while the black histogram displays the PDF extracted from the REFERENCE catalogues. The blue diamonds with lines and the magenta triangles each show the Γ_e expansion performed in the REFERENCE and MOCK catalogues, respectively. On the other hand, the cyan diamonds with lines and the orange triangles show, respectively, the SLN expansion performed in the REFERENCE and MOCK catalogues. Bottom: relative deviation of the Γ_e and SLN expansions applied to both the REFERENCE and MOCK catalogues with respect to the PDF of the REFERENCE catalogues.
