Monte Carlo-derived multiplicative normalization corrections for the polarization reconstruction, using inhomogeneous filtering (blue points). Band powers are divided by these numbers to provide our final estimates. This correction is not small, and is sourced by the large spatial variation of the estimator response; however, it is very well reproduced by the approximate analytic model of Eq. (21), shown as the dashed blue line. The correction for our baseline MV band powers using homogeneous filtering is shown as the orange points.
