Extracting radiation source function and calculating power spectrum in flat sky limit

Post by Nazanin Saadat Mogh » June 16 2019

Hi!
I’m trying to calculate CMB bispectrum and I get radiation source function from CAMB. I calculate every thing within flat sky limit. for this purpose I need to calculate CMB TT EE and BB power spectrum within flat sky limit. TT power spectrum is compatible with CAMB TT power spectrum for ell>40. But EE and BB power spectrum, according to my calculations, are not quiet compatible with CAMB’s results.
I'm not quiet sure if the problem is with my calculation or I'm getting the wrong source function
It would be highly appreciated if you could advise me on this topic.
thank you in advance
