CMB constrins zeq, omegab h^2, angular scale of the sound horizon, theta_D (angular scale of diffusion damping?!, look at Eisenstein Hu papers).

zeq gives ratios of Matter density and Radiation density. Neff causes addition to radiation density, therefore degeneracy with Omega_m.

Combined a number of different cosmological probes and extended parameter models.

Different SN light curve fitters give different results.
