Testing the sensitivity of η to the bias of the adopted tracers. Clustering statistics are estimated from two sub sets of the halo simulated catalogues, known as mid and low sub-samples tant include haloes with masses limited to M < 1013 h-1 M⊙ and M < 1012 h-1 M⊙, respectively. The left and right panels show the relative variation in the variance (upper), correlation function δξ ≡ ξg,R/ξg, R, ref − 1 (central), and clustering ratio δη ≡ ηg,R/ηg, R, ref − 1 with respect to the measurements from the full mock catalogues that contain all haloes with masses up to M = 7 × 1014 h-1 M⊙ for these two catalogues. In the left panel, quantities are measured from the Bh halo catalogues in real space, while the measurements on the right are performed in redshift space using the Lh light-cones. Error bars are estimated using the dispersion among the mock catalogues. For the sake of clarity, a relative shift along the abscissa is applied to the data in the bottom plots.
