Contributions to the additive systematic $\delta {\xi }_{+}^{\mathrm{sys}}(\theta )$ from the Paulin-Henriksson et al. (2008) systematics model. The various lines show the four components, with their summation in thick blue-green. The yellow band depicts 10% of the cosmic shear uncertainty on ξ₊. The figure is linear between the black dashed lines, and logarithmic outside. This demonstration is for tomographic bin six, but all bins show quantitatively similar results.
