Comparison of DLL simulations with original (number count 128³) and higher resolutions (number count 212³) against high-resolution κTNG-Dark simulations. Left panel: Angular power spectra of PM simulations with original resolution (blue line) and higher resolution (red line) compared to the κTNG-Dark prediction. Right panel: fractional angular power spectrum of PM simulations with original and higher resolution and the κTNG-Dark prediction. The power spectra and ratios are means over 100 independent map realizations and the shaded regions represent the error on the mean. The spectra are computed for the source redshift z_s = 0.91.
