Cosmological parameters constraints

• CCCP likelihood grids (108Mb)
  
• CosmoMC module to interpolate in these likelihood grids (readme).

• WMAP7 -- 7 year WMAP data (Larson at al., 2011)
• SPT -- CMB power spectrum from SPT (Keisler et al., 2011)
• H0 -- Determination of Hubble constant (Riess et al., 2011)
• BAO -- SDSS and 2dF baryon acoustic oscillations measurements (Percival et al., 2010)
• SN -- UNION2 Type I-a supernovae dataset (Amanullah et al., 2010)

• ΛCDM -- flat Universe with cosmological constant
• f_ν -- with massive neutrinos (three massive species)
• f_ν(1) -- with one massive neutrino
• N_eff -- with free effective number of neutrino species, > 3.046
• dn/dlnk -- with free running spectral index
• r -- with tensor modes
• Y_He -- with free primordial helium abundance
• OΛCDM -- curved Universe
• WCDM -- flat Universe with dark energy
• OWCDM -- curved Universe with dark energy
• WACDM -- flat Universe with dark energy, time-dependent equation of state
