Accuracy of the parametric model and FORESTFLOW in describing P_× measurements from the CENTRAL simulation at z = 3. Dots show simulation measurements, dashed lines depict predictions from the best-fitting parametric model to P_3D and P_1D measurements, and solid lines and shaded areas display the average and 68% credible interval of FORESTFLOW predictions. The color of the lines indicates the results for different bins in transverse separation r_⊥. The middle panel shows the residual between simulation measurements and the best-fitting parametric model, while the bottom panel displays the residual between predictions from the parametric model and FORESTFLOW. The performance of FORESTFLOW in reproducing simulation measurements is similar to that of the best-fitting model.
