pycamb BB power spectrum
Posted: March 12 2016
Hi,
I was using pycamb to calculate BB power spectrum up to l~200. I set:
params.WantTensor = True
params.NonLinear =2
params.AccurateBB=1
However, I found that the shape of the power spectrum (even at low l) depends greatly on lmax. To get accurate BB, I needed to set lmax to as great as ~3000. I was wondering if there is some other setting I can use to achieve accuracy without spending too much computing power.
Thanks,
Yajing
