Residual shear bias introduced by the shear-interplay effect (orange points) as a function of the true redshift estimated from the blending-only simulations. The residuals are calculated from , with the shear bias from the blending-only variable shear simulations and the shear bias from the blending-only constant shear simulations. The error bars correspond to the fitting uncertainties reported by the linear regression. They are driven by two factors: the number of objects used by the fitting and the amplitude of the input shear value. The dashed lines show the normalised number density with respect to redshift.
