... values

Note that Ikebe et al. (2002) and RB02 demonstrated that even for a local cluster sample; i.e., without information on cluster abundance evolution, the degeneracy between $\Omega_{\rm m}$ and $\sigma_8$ can be broken through the shape of the mass function (the resulting direct best fit values from the RB02 mass function are consistent within the statistical uncertainties with the new cosmology).
