COMMENT
COMMENT Wilkinson Microwave Anisotropy Probe (WMAP) year 1 data release.
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 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.
