Warm-up exercise for delensing
Kyle has provided a first set of "perfect" B-mode templates. These are simply a masked map of B-modes extracted from the FFP10 simulations. The goal was to adjust analysis tools so they are able to include B-mode templates in this format.
The figure shows the lensed LCDM spectrum and the "delensed" version.
The residual is below 0.001, except in the lowest bins. We plan to investigate if the rise in the first bin disappears if the template covers a somewhat larger fraction of the sky than the low resolution data.
