30 GHz TT, EE, and TE spectra with white noise included. The TE spectra have been binned over 20 multipoles. The deconvolution results are shown for three combinations of parameters: k_max = 4 and l_max = 600, 700 (purple), and k_max = 6, l_max = 6 (red). The spectrum of a naive binned map is shown in green. The blue line shows the spectrum of the binned map corrected for a symmetric beam. The corresponding noise-free result is shown with dashed linetype in the TT plot, to indicate the region where noise begins to dominate over signal.
