COMMENT WMAP Theoretical Power Spectrum based on an LCDM model with a COMMENT scale-dependent (running) spectral index which best fits the COMMENT dataset composed of WMAP, CBI and ACBAR CMB data combined with COMMENT 2dF and Ly-alpha 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 = 0.02262 COMMENT omega_cdm h^2 = 0.10861 COMMENT n(k=0.05) = 1.04173 COMMENT exp(-2tau) = 0.69879 COMMENT dn/dlnk = -0.01618 COMMENT amp(k=0.05) = 0.86746 COMMENT h = 0.73070 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. See the HEALPix homepage (http://www.eso.org.science/healpix) COMMENT for details about SYNFAST. COMMENT REFERENC= 'WMAP Explanatory Supplement: http://lambda.gsfc.nasa.gov/' END
