Projected correlation function (w_p), monopole, and quadrupole of the galaxies of the TNG300 simulation (black, 1σ interval in grey) and the model (red) for an SFR-selected subsample with number densities n = 10⁻² (straight), 10^−2.5 (dashed), 10⁻³ (dash-dotted), and n = 10^−3.5 (dotted) h³ Mpc⁻³ at z = 1. The three lower number densities have been shifted on the upper panel along the y-axis for visualisation purposes. The lower panel shows the relative difference between the fits and the model normalised by the uncertainty on the measurement on TNG300, with the grey-shaded region indicating 1σ. The green-shaded region (r < 0.6 Mpc/h) indicates the region not considered in the parameter fitting.
