γ-2PCF ξ₊ (top) and ξ₋ (bottom) DVs and derivatives. The gray lines, whose scale is given by the second axis, correspond to the average DVs computed from the 924 SLICS realizations. The Fisher derivatives (defined in Eq. (47)) are computed from the DUSTGRAIN-pathfinder simulations with large variations of Ω_m (orange), σ₈ (green), and w (blue). The solid, dashed, and dotted lines respectively correspond to the average over 128, 64, and 32 realizations. The shaded areas represent the uncertainty computed from the 128 DUSTGRAIN-pathfinder realizations, and the gray error bars those of the 924 SLICS realizations. The inclusion of the dashed and dotted lines within the shaded areas highlights the low numerical noise.
