Comparison of images restored with and without considering systematic image motions. Top: images in the red wing of the FeI line at 6302.5 Å in the four Stokes parameters. Ticks on both axes indicate the angular size of the FOV in arcseconds. Bottom: same images as shown in the top panels, but with the motion-induced crosstalk removed by realigning the images for each of the modulated states and subtracting the remaining residual I to Q, U, and V crosstalk, averaged over a 20 min period.
