Figure 11: Marginalized γ − Σ 0 forecast for weak lensing only analysis with Euclid. Here Σ 0 is defined from Σ = 1 + Σ0a and Σ, defined via Eq. 1.3.28View Equation, is related to the WL potential. Black contours correspond to ℓmax = 5000, demonstrating an error of 0.089(1σ) on Σ0, whereas the red contours correspond to ℓmax = 500 giving an error of 0.034. In both cases, the inner and outer contours are 1σ and 2σ respectively. GR resides at [0.55, 0], while DGP resides at [0.68, 0].
