usage of pantheon data

[ming-jian]

Dear everyone,
I note that the six cosmological parameters are fixed in the Pantheon_plus.param of input file.  The details are as follows:

Fixed cosmological parameters

data.cosmo_arguments['n_s'] = 0.96
data.cosmo_arguments['ln10^{10}A_s'] = 3.05
data.cosmo_arguments['tau_reio'] = 0.06
data.cosmo_arguments['Omega_b'] = 0.0468

Three massive neutrinos with sum(mnu)=0.06eV and Neff = 3.044

data.cosmo_arguments['N_ur'] = 0.00441
data.cosmo_arguments['N_ncdm'] = 1
data.cosmo_arguments['deg_ncdm'] = 3
data.cosmo_arguments['m_ncdm'] = 0.02
data.cosmo_arguments['T_ncdm'] = 0.71611

Whether we should be required to fix these cosmological parameters in constraining the dark energy models?
