There are three COMMENT components to the model: COMMENT 1) The modeled CMB contribution to the sky provided in Stokes I and in COMMENT Stokes Q and U polarization signals. COMMENT 2) The Galaxy Stokes I model; a signal is provided for each of COMMENT the four WMAP channels. COMMENT 3) The Galaxy polarization model provided as Q and U signals. COMMENT These models are in the form of HEALPix resolution 10 skymaps, smoothed COMMENT to a beam response appropriate for the differencing assembly indicated COMMENT by the DA keyword. Each of these three components is provided in a COMMENT separate FITS binary table extension in this file.
