Convergence power spectra for sources at z_s = 2. From left to right, we exhibit the runs that account for Ω_m, σ₈ and w variations, respectively. The curves show the average over all 128 line of sight realizations, and the gray areas show the scatter of the convergence power spectrum around the mean value for the reference ΛCDM simulation (256 lines of sight) considering a field of view of 5 deg on a side.
