Notes. We have used the configuration with the maximum set of nuisance parameters that we consider, i.e. NK = NZ = 7. The cuts in angular frequency for number density correlations have been applied to restrict the analysis to the linear regime. Shown are the results using shear-shear correlations ϵϵ only, observed galaxy clustering correlations nn only, all correlations, and the lensing-only signal (assuming no intrinsic alignments). The left-hand part of the table uses the standard Euclid-like survey parameters, i.e. σϵ = 0.35, n = 35 arcmin-2, and the survey area A = 20000deg2. The right-hand part of the table uses parameters for a DES-like survey, i.e. σϵ = 0.23, n = 10 arcmin-2, and the survey area A = 5000 deg2.
