Hi.
I have just simple question.
In subroutine initial, equations.f90 in CAMB,
what does y(EV%g_ix+1) mean?
I know y(EV%g_ix) is clxg, and this is density perturbation of photon.
But I don't know about y(EV%g_ix+1).
Just differential value about tau?

Any help would be appreciated.

Code: Select all

    
!  Photons
    y&#40;EV%g_ix&#41;=InitVec&#40;i_clxg&#41;
    y&#40;EV%g_ix+1&#41;=InitVec&#40;i_qg&#41;

It's the L=1 moment (the photon heat flux).

Thank you very much for your answer.
