Comparison of the simulation-based N⁽¹⁾ lensing bias estimates (blue points) to analytic estimates in the case of our inhomogeneously-filtered polarization reconstruction. The orange curve shows the naive prediction using a single map-averaged noise level, which does not capture the variation of the N⁽¹⁾ bias across the sky. The green curve shows the weighted average Eq. (80). The black line shows the fiducial lensing power spectrum.
