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 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   =  0.02200
COMMENT      omega_cdm h^2 =  0.11294
COMMENT      n(k=0.05)     =  0.90226
COMMENT      exp(-2tau)    =  0.58862
COMMENT      dn/dlnk       = -0.04160
COMMENT      amp(k=0.05)   =  1.00602
COMMENT      h             =  0.71091
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.
