Points showing the transverse ξ_⊥(s) and parallel ξ_‖(s) components of the 2pcf computed using ConKer with three values of grid spacing g_S = 8 (red–yellow), 4 (purple–green), 2 (black–grey) h⁻¹ Mpc. Solid lines in the corresponding colors show the results from the nbodykit 2pcf algorithm. This figure corresponds only to NGC galaxies. The error bars and shaded regions are determined from the ensemble of Patchy mocks. The lower subpanels show the residual between the two methods.
