Neutrino mass in COSMOMC.

[charles jose]

The default downloaded version of COSMOMC constrains neutrino fraction f_\nu rather than neutrino mass m_\nu. Here we need to specify the limits on f_\nu in the params.ini file. I would rather constrain m_\nu rather than f_\nu. So I made the following modifications.

I just reinterpreted f_\nu as m_\nu in params.ini file. So I specified the limits of m_\nu to this parameter (parameter 6).

In SetForH(Params,CMB,H0) (params_CMB.f90 subroutine) I modified the equation for CMB%omnuh2 as follows.
CMB%omnuh2 = CMB%nufrac/93.1. (\Omega_\nu h^2 = m_\nu/93.1)
Here CMB%nufrac = Params(6) is the newly interpreted neutrino mass (previously it was f_\nu) .

Can somebody please tell me that these modifications are enough so that I will get m_\nu in chains other than f_\nu.

Thanks in advance.
