Comparison of two star-galaxy cross-correlation functions with their corresponding linear systematics model predictions (Eqs. (15) and (16)) for the five tomographic bins. The star-galaxy cross correlation function (dark blue) is in reasonable agreement with the model (blue bar), where the width of the model reflects the 2σ uncertainty. The residual star-galaxy cross correlation function (shown pink), and corresponding model (grey), are scaled by a factor of ten in order to display the measurements on the same scale. We also scale the correlation functions by to aid visualisation of the large-scale signal.
