COMMENT WMAP Theoretical Power Spectrum based on an LCDM model with a COMMENT power-law spectral index which best fits the dataset COMMENT composed only of WMAP, CBI and ACBAR CMB data. COMMENT The cosmological parameters used to generate this model are COMMENT listed below. For a more detailed explanation of parameters, COMMENT see Spergel et al. (2003, astro-ph/0302209). The values below COMMENT are the maximum likelihood values from the full N-dimensional COMMENT likelihood analysis and may differ slightly from the COMMENT marginalized values quoted in Spergel et al.: COMMENT omega_b h^2 = 0.02238 COMMENT omega_cdm h^2 = 0.11061 COMMENT n(k=0.05) = 0.95820 COMMENT exp(-2tau) = 0.80209 COMMENT amp(k=0.05) = 0.73935 COMMENT h = 0.71992 COMMENT COMMENT Note that EE data were not included in the model fits, so the COMMENT EE spectrum should be regarded as a prediction. COMMENT COMMENT This FITS file was generated from the Version 1 (April 2003) ASCII COMMENT data file in order to provide a format compatible with SYNFAST COMMENT input.
