This posting follows from 20180827_bkfinal_04 and shows results for three masks: 04 is nominal 3% circular, 04b is nominal Chile and 04c is Pole (BICEP3 2017).

We show results for all the available foreground models which cover the full sky. These are: Uniform Gaussian 00, PySM models 01/02/03, amp mod Gaussian 07, MKD multilayer 08 (arxiv/1706.04162), and Vansyngel 09 arxiv/1611.02577).

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

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.
