Stokes I and V profiles of Fe i 525.02 nm corresponding to pixels #1 (top) and 2 (bottom) in Fig. 1. The solid and dashed lines represent the original simulations and the maps degraded by telescope diffraction and CCD pixelation, respectively. The vertical lines indicate wavelength samples at  [  ± 8,  ± 4 ]  pm from the central wavelength of the line. To make a pixel-to-pixel comparison, we have taken the Stokes profiles from the degraded data before binning the images to match the IMaX CCD pixel size. Therefore, dissimilarities are enhanced.
