This posting follows from 20181029_bkfinal_02lt and adds reconstructed lensing templates from Julien Carron which are described here.

To make this set I have resorted to a kludge. Julien provides the lensing template as reconstructed from signal+noise and signal alone. I take the map noise realizations as the signal+noise minus the signal. In the pager below this appears to work well. It is not required that the signal+noise spectrum correctly debias when the noise spectrum is subtracted - but it appears to. I will investigate more later.

Note: The contours mark the simulated bandpower in each bin closest to the respective percentile.


sum bp devs


Note: Remember that bandpower is a variance. Hence bandpower error bar is the std of a variance. This means noise and sample fluctuation components straight add, no quadrature — i.e. the difference between blue and red is the signal fluctatution component.
