Declaration [src]

gdouble
nc_hicosmo_H_number_density (
  NcHICosmo* cosmo
)

Description [src]

Calculates the Hydrogen-1 number density $n_\mathrm{1H} = Y_{\mathrm{1H}p} n_{b0} / m_\mathrm{1H}$ using nc_hicosmo_Yp_1H() $\times$ nc_hicosmo_baryon_density() / ncm_c_rest_energy_1H().

Return value

Type: gdouble

The baryon density $n_\mathrm{1H}$.
