Comoving number density n_g in h³ Mpc⁻³ of galaxies as a function of redshift for the Geppetto (orange) and EuclidLargeMocks (red) catalogues, compared with the Flagship catalogue (dark blue points). For the sets of Pinocchio catalogues we give the average number density as a continuous line and its standard deviation as a shaded area, while Flagship values, reported as circles, are assigned the EuclidLargeMocks variance, reported as an errorbar. We show in the top panel results for three limiting fluxes, f_Hα > 0.5f₀, f₀, and 1.5f₀. The other panels give, for each limiting flux, the residuals (n_g/n_model 3 − 1) in percent of simulated number densities with respect to model 3 from Pozzetti et al. (2016). The black lines denote the zero value of the residuals.
