Density C_ell without the growth factor contribution D(z)^2 #307
I was wondering if there is a straightforward way to run CLASS (v2.6.3) nCl density without the contribution of time in the density source (equivalent to omitting D(z)^2). Since the source terms of CLASS are function of tau, I have been trying to replace tau=tau0 by modifying source[index_tau]= rescaling at line 2494 of transfer.c, such that sources[tau_size -1] *= rescaling, but the result is not what I would expect.
