Assumptions:

WMAP 9 year data

Explanation

The Wilkinson Microwave Anisotropy Probe measured the temperature
and polarization of the CMB over the full sky in the K, Ka, Q, V, and W
microwave bands.

The WMAP produced this likelihood code, which takes in theory spectra
for TT, EE, BB, and TE spectra and compares it to WMAP data.

The method used for the likelihood is different in different ell regimes
and for different spectra.

##Parameters

These parameters can be set in the module's section in the ini parameter file.
If no default is specified then the parameter is required.

Parameter	Description

##Inputs

These parameters and data are inputs to the module, either supplied as parameters by the sampler or computed by some previous module. They are loaded from the data block.

Section	Parameter	Description
cmb_cl	ell	Integer vector of angular frequencies for CMB spectra
	tt	Double vector of temperature spectra in l*(l+1) C_ell / uK^2 (if using TT data)
	ee	Double vector of E-mode polarization spectra in l*(l+1) C_ell / uK^2 (if using pol data)
	bb	Double vector of B-mode polarization spectra in l*(l+1) C_ell / uK^2 (if using pol data)
	te	Double vector of cross spectra in l*(l+1) C_ell / uK^2 (if using pol data)

##Outputs

These parameters and data are computed as outputs from the module

Section	Parameter	Description
likelihoods	wmap7_like	Combined log-likelihood from all WMAP components
