I want to have a parameter that acts like Alens but without its effect on the lensing power. In other words I want it to act only on the TT power spectrum. What should I modify to achieve this? Will modifying the following lines in camb/cmbmain.f90 be enough?
-------------------------------------------------------
Code: Select all
if (CTrans%NumSources>2) then
iCl_scalar(j,C_Phi,pix) = ALens*iCl_scalar(j,C_Phi,pix)*fourpi*ell**4
!The lensing power spectrum computed is l^4 C_l^{\phi\phi}
!We put pix extra factors of l here to improve interpolation in CTrans%ls%l
iCl_scalar(j,C_PhiTemp,pix) = sqrt(ALens)* iCl_scalar(j,C_PhiTemp,pix)*fourpi*ell**3
!Cross-correlation is CTrans%ls%l^3 C_l^{\phi T}
iCl_scalar(j,C_PhiE,pix) = sqrt(ALens)* iCl_scalar(j,C_PhiE,pix)*fourpi*ell**3*sqrt(ctnorm)
!Cross-correlation is CTrans%ls%l^3 C_l^{\phi E}
Thanks,
