Query: Cosmic Complementarity: Joint Parameter Estimation from CMB Experiments
  and Redshift Surveys   We study the ability of future CMB anisotropy experiments and redshift
surveys to constrain a thirteen-dimensional parameterization of the adiabatic
cold dark matter model. Each alone is unable to determine all parameters to
high accuracy. However, considered together, one data set resolves the
difficulties of the other, allowing certain degenerate parameters to be
determined with far greater precision. We treat in detail the degeneracies
involving the classical cosmological parameters, massive neutrinos,
tensor-scalar ratio, bias, and reionization optical depth as well as how
redshift surveys can resolve them. We discuss the opportunities for internal
and external consistency checks on these measurements. Previous papers on
parameter estimation have generally treated smaller parameter spaces; in direct
comparisons to these works, we tend to find weaker constraints and suggest
numerical explanations for the discrepancies.
