Ideal delensing templates from flat-sky QE, first pass
This page presents first-pass results on creating lensing B templates from ideal simulation inputs using a flat-sky quadratic estimator.
One B template from sim_0000, projected back to the full sky:
In the spectrum plot, I show the auto-spectra and cross-spectrum between two types of lensing b templates:
- "Bproj" are directly projected blm maps. These are the "truth" maps (up to curved-to-flat sky projection issues)
- "QE" are estimates using a flat-sky quadratic estimator with perfect E and phi inputs.
