Satellite count N_s, 200c vs. halo mass M_200c for three Magneticum simulations, Box4/uhr (blue coloured and moved slightly down to improve readability), Box2/hr (green coloured), and Box0/mr (red colour) to account for resolution effects. Data points represent single haloes and coloured lines represent average values per mass bin. The black line is the emulator prediction, and the shaded area corresponds to the relative uncertainty from Poisson distribution. Emulator and Box0/mr data are rescaled with Eq. (3).
