In this posting, we plot the bandpower window function as computed by our S4 analysis pipeline.
Comments on the figure:
- We see that the Chile mask is the one that has the larger upturn at low-\(\ell\).
- For the large, low frequency beams, it is a percent level contribution compared to the peak for the highest bandpower.
- The Pole case has wider window functions, but they have the least contributions at low ell.
- The circular mask is in-between.
