Normalised histogram of the ratio between the difference between emulated and exact modelling 2PCF predictions and the corresponding uncertainty, Δ_ξ/σ_ξ (top four panels). Different colours refer to different redshift snapshot, while the dashed black line represents the median of the distribution. The same quantity for the 3PCF, Δ_ζ/σ_ζ, is shown in the bottom four panels, for the different redshifts.
