2σ contours derived for one single source redshift at z = 0.91 and the survey setup presented in Section 4. We compare the Fisher matrix constraints on cosmological parameters and A_IA amplitude obtained with the C_ℓ from our mock maps (orange) and the theoretical C_ℓ (blue) obtained from the public library https://github.com/DifferentiableUniverseInitiative/jaxcosmo (Campagne et al. 2023). In both cases, the constraints are obtained by applying the wavelet pass-band filter for the C_ℓ as described in Section 4. The dashed black contours are the prior used for the forecasting.
