Final pager
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.

Legend for first half of the "Figure types":
- Thick red : lensed-ΛCDM scalars
- Thick black : Real data
- Colored : lensed-ΛCDM + noise + foreground realizations
Legend for second half of the "Figure types":
spectra
- thick red : lensed-ΛCDM
- thin gray : s+n+f simulations with lensed-ΛCDM (sim type 5) and foregrounds (sim type 3) as signal, debiased with noise (sim type 6)
- thick gray : mean of sims (thin gray)
- red points with blue error bars : real data, debiased with the noise, uncertainties from the spread of the s+n+f sims (thin gray)
bp devs
- thin gray : s+n+f sims
- thin red : 1 sigma contours
- thin green : 2 sigma contours
- thick black + markers : real data
- red markers : bins that go into chi2 analysis
Note: The contours mark the simulated bandpower in each bin closest to the respective percentile.
chi2
- red vertical : real data
- blue : distribution from s+n+f sims
- green : chi2 probability distribution fitted to blue
sum bp devs
- red vertical : real data
- blue : distribution from s+n+f sims
uncertainties
- red : std of s+n+f sims
- blue : std of noise-only sims
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.
