Kyle has provided a first set of "perfect" B-mode templates. At this point these are simply a masked map of B-modes extracted from the FFP10 simulations.

The goal was simply to make sure the analysis tools can incorporate B-mode templates in this format.

The figure shows the lensed LCDM spectrum and the "delensed" version.

The residual is below 0.1%, except in the lowest bins. We plan to investigate if the rise in the lowest bins disappears if the template covers a somewhat larger fraction of the sky than the low resolution data.
