Computers and software • CAMB: Setting massless neutrino density to zero

$

Hi,

I'm trying to get familiar with using CAMB, so I would like to figure out its details with only a simple cosmological model where there are only matter, dark matter, and photons. I managed to remove massive neutrinos by setting mnu=0 in camb.CAMBparams.set_cosmology(). But I couldn't find a parameter that lets me to remove the massless neutrinos. Is it possible to remove the massless neutrino component in using CAMB? If yes, how can it be done?

Thanks!
Rui
