Cross-correlation measurements for the z_spec and z_ph foreground samples using the mini-Tile and Tile schemes. Left panel: measurements before any large-scale bias correction. The z_spec mini-Tile case exactly matches the measurements analysed in BON20. Right panel: same measurements after the corrections are applied. The model predictions using the best-fit values for the z_spec sample (solid black line) and the z_ph sample (dashed green line) in the mini-Tile scheme are also shown (see text for more details).
