CAMB--Display of individual terms in the angular power spectrum

Post by Nicolò Dalmasso » February 24 2021

Hello everybody,

I'm working using CAMB for my thesis in Astrophysics and I need to view and separate the single terms wich are contained in the angular power spectrum precisely in the Δl(z,k) calculation that goes in to the Cl(z1,z2). In a specific way I need to focus on three terms: magnification bias, RSD and gravitational lensing.

The question is: where do I have to look or how i can, through the code, isolate and study these three terms alone?

Thanks in advance.

You can generate spectra with different settings for what's included, see

Thank you for the reply.

I've another question: by using "counts_redshift" I can calculate the angular power spectrum with or without RSD, but there is a way to get (f = RSD growth rate) directly from CAMB?
