Maps of the recovered χ^E (upper row) and χ^B (lower row) fields as defined in Zaldarriaga & Seljak (1997) (left column) and difference maps normalized by the input map rms, , Eq. (23), computed for (ℓ_max,1,ℓ_max,2) = ⁽4000,2000⁾ (middle column) and (ℓ_max,1,ℓ_max,2) = ⁽8000,4000⁾ (right). There is a factor of 10 difference between the color scales of the middle and left column.
