Fisher forecasts for all probes computed for a Euclid-like survey without tomography. The different ellipses refer to different numbers of DUSTGRAIN-pathfinder realizations N_c used to compute the DV derivatives: dotted, dashed, and solid lines, respectively for 32, 64, and 128 realizations. The covariance matrix is held fixed to SLICS with N_f = 924 realizations. For γ-2PCF and κ-PDF we separately assess the convergence of derivatives by a comparison with theoretical predictions in Figs. 17 and 18.
