BB Spectra Comparison: d1, d10, d12

[brandonshensley]

I have put together a quick notebook comparing the BB spectra of the d1, d10, and d12 models on the SO SAT mask at both 353 and 150 GHz. Comments welcome, but here are a few quick takeaways from me:

• There is reasonably good agreement between d1 and d10 on this mask out to ell of ~100. d12 seems to have systematically less BB than d1 except at the very largest scales
• The d10 BB spectrum is much steeper than either d1 or d12, as we knew
• Certainly there is a change in slope in d10 around ell ~ 100, but there isn't a dramatic feature at least over this mask
• The spectra are very similar between 150 and 353 GHz, suggesting to me that spectral parameter variations don't account for much of the differences we are seeing

Overall this comparison looks fine to me, a good snapshot of current uncertainties. It will be useful to see such plots for other masks, please do feel free to use the notebook (and let me know if you find any bugs!).
