Polarimetric fringes in the reduced data. Ticks on both axes indicate the angular size of the FOV in arcseconds. Left: Stokes / image in the red wing of the FeI line at 6302.5 Å. Center, continuum-corrected Stokes V image corresponding to the right image, reduced with an unpolarized gain correction. Right: same image as in the center panel, but reduced using a polarized gain correction.
