Stokes I, Q/I, U/I, and V/I images (left) and spatially averaged profiles (right). The spatial average was performed over the slit positions from ∼110″ to 170″ (dashed line) where the magnetic field is strongest. The intensity is normalized to the continuum. The observation was taken at a limb distance of 5″, across a solar region with stronger magnetic activity, with the slit oriented parallel to the nearest limb. The positive direction for Stokes Q is taken parallel to the limb. The wavelength intervals of interest are highlighted in the intensity and Q/I images.
