The impact of variable depth in KiDS-1000 on the cosmic shear real-space two-point correlation functions, ξ(θ) in the autocorrelation of the S5 bin. The blue line shows the difference in the mean signal from 5,000 realisations of the anisotropic systematics model with variable depth versus the mean signal from the same number of realisations when assuming that the observational depth is isotropic. The orange line shows the same difference in signal as predicted for KiDS-1000 by the analytical model in Heydenreich et al. (2020). We note that variable depth constitutes approximately 1% of the measured cosmic shear signal in KiDS-1000.
