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.
