Form top to bottom: maps in intensity, I, and polarization Q and U at 23 GHz for the WMAP 5-year data (left) and the model of synchrotron emission with MLS magnetic field for the best fit model parameters (right) and at 353 GHz for the Archeops data (left) and the model of thermal dust emission with MLS magnetic field for the best fit model parameters (right). The 353 GHz maps are rotated by 180° for better visualization. All the maps are in K_RJ units.
