CAMB: remove neutrino
Posted: June 11 2018
Hi.
I'm a little confused about massless neutrino.
I set the neutrino parameter like this:
omnuh2 = 0.000
massless_neutrinos = 0.0
nu_mass_eigenstates = 0
massive_neutrinos = 0.
share_delta_neff = F
nu_mass_fractions = 0.
nu_mass_degeneracies = 0.
because I want to remove massless and massive neutrinos.
and I checked that massive neutrino's value is zero.
But massless is not.
Although I check that 'CP%Num_Nu_massless' is zero, but for density perturbation and Delta_r/k^2 in transfer.dat output file, massless neutrino has non-zero value.
How can I remove all neutrinos?
Or are massless neutrinos always calculated?
Any help would be appreciated.
