Bias as a function of Σ₈ for different filters. Blue dots, red pluses, and green crosses are respectively the bias of a specific S/N bin [4.0, 4.5] under different cosmologies for a Gaussian filter of 1.2, 2.4, and 4.8 arcmin. Instead of visualizing on the Ω _m – σ₈ plane, here we chose a one-dimensional representation by the reduced parameter Σ ₈. As a result, blues dots contain exactly the same information as the left panel in Fig. 2 and red pluses the same as the right panel.
