Posterior summary maps for the LFI 30 GHz channel. Columns show the temperature and Stokes Q and U parameters, while rows show, from top to bottom, the posterior mean, the posterior standard deviation, the white noise rms per pixel, and the difference between two random individual Gibbs samples. The polarization maps in the two rows have been smoothed to an angular resolution of 1° FWHM to visually reduce the noise level, while the bottom row is smoothed to 7° FWHM.
