Convergence power spectra with AMR (red) and without (blue) at z = 0.45, using Healpix with N_side = 2048. The black line is the theoretical prediction computed using NlCAEA (Kilbinger et al. 2017) with HALOFIT (Smith et al. 2003) parameters fitted on our simulation. When AMR is accounted for, we have a nice agreement between the numerical results and theoretical prediction. When it is not, the power spectrum experiences a damping at small angular scales (high where the discrepancy becomes large already at ℓ ≈ 300.
