Predicted shear profiles for the two lens samples (dashed black line) and measured shear profiles (in orange) for the new model with filter U. The orange shaded region is the standard deviation on the mean from 48 sub-patches, scaled to the KiDS-1000 area. The residuals between model and simulations were tested to determine whether they can be erased when the PDF of the aperture number is fixed to the measured value from T17, but the same discrepancies were present.
