Neutrinos in CAMB

Post by Anais Rassat » July 07 2009

Hi Anthony & others,

I have a question about the neutrino parameters in the params.ini file in CAMB.

I would like to calculate the power spectrum for 3 massive neutrino species, each with the same mass.

In this case, should my CAMB neutrino parameters be set as:

massless_neutrinos = 0.
massive_neutrinos = 3.
nu_mass_eigenstates =1
nu_mass_degeneracies = 0
nu_mass_fractions = 1

Thanks, Anais.

Yes, I think that's right.

btw, I still disagree with your redshift distortion paper...
