WMAP CMB

Using five year WMAP full sky observations at 23, 33, 41, 61, and 94 GHz, and the 100 micron IRIS map, we estimate the full sky CMB temperature anisotropies via a set of localised minimum variance linear combinations on a frame of spherical needlets. We obtain two full sky, low foreground contamination maps of the CMB, one at the resolution of the WMAP W channel, and a Wiener-filtered version at lower effective resolution, but with minimum integrated error.
