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(EV%g_ix)=InitVec(i_clxg) y(EV%g_ix+1)=InitVec(i_qg)
