fix sign of BB spectrum term in EB response #2

Thanks @cmbant for fixing this error! Do you know what would be the impact of this change? I remember we always had the highest level of mismatch concerning the BB & EB terms in 1611.01446 (sims vs theory).

JulienPeloton commented 5 years ago

Looking at the equation, I guess the impact scales as CB/CE, so more pronounced at very small scales where lensing is the dominant part of both spectra?

cmbant commented 5 years ago

I think it's about 1-2% in the phi responses for S4. I didn't look at how it enters as a function of ell_cmb.

Thanks! Merging.
