Planck 353 GHz maps of the Polaris Flare molecular cloud. The top row shows, from left to right, the total intensity I₃₅₃ on a logarithmic scale, the Stokes Q₃₅₃ map and the Stokes U₃₅₃ map, while the bottom row shows the polarization fraction p_MAS, the polarization angle ψ, and the polarization angle dispersion function . The τ₃₅₃ and T_obs maps have the same aspects as the I₃₅₃ map but with their own scales.
