This post is similar to Correlation_of_reconstructed_lensing_template_to_ideal II and Correlation of reconstructed lensing template to ideal for 06b.00

We have made DSR config map based sims as set 06 | 20191101_dc06_specsmaps

Julien Carron ran a new iterative reconstruction on the 95GHz lensed-LCDM realizations with noise added. Note that he did not use the "comb" files which also include foreground - he manually added the "llcdm" and "noise" files provided. Julien described these reconstructions in Iterative curved sky s06b nofg lensing templates

The plot below show the Q map for the first realization - looks sensible - the right sky area. Can't really see noise increasing towards the edge of the patch.

I next take the cross correlation of the B-modes versus the ideal template (where ideal is lensed-unlensed inputs). The plot below shows the results averaging over the first 10 realizations.

We should focus on the ell<200 part which is relevant for r limits. Note that the recon from signal only is not the "best the QE method can do" - it is still using the same weights as the signal+noise recon so is disguarding some high ell information. However, we know from Correlation_of_reconstructed_lensing_template_to_ideal II that the algorithmic ceiling is 0.8-0.9.

I request that Julien run his recon on the 06c and 06d coverage patterns and for the 07 and 09 foreground models.
