# S4 Inflation Chapter Plot Suggestions, v2

## 2015-07-07  (Victor Buza)

This is a follow-up posting on this, showing "$$\sigma_r$$ vs Effort" and "$$\sigma_r$$ vs $$f_{sky}$$," plots, as well as a few versions of the "$$C_l^{BB}$$" plot. Aside from stylistic updates, there are two main changes from the last posting:

• First, even though the current optimization prefers f_sky=1% as the minimum for the r=0 case, perhaps in reality we’d like to do something slightly larger. We’re proposing to switch to f_sky=3% as the default scenario. One consequence of this would be reducing the delensing level from 95% power to 90% (i.e. go from 5% residual lensing power, to 10%). This is what's currently in the Science Book.
• Looking at models of interest on the r-ns plots, and through the text, it seems that r=0.003 is perhaps a better choice for the $$r>0$$ model. There is a class of models at that level, and it is possibly the lowest r we could sensibly detect. This is not yet in the Science Book, but is presented below.
