Stokes profiles of selected pixels from area C1. The upper row displays 2D maps, which from left to right show continuum intensity, and blue- and red-wing magnetograms constructed from the first spectral line at −215 and +215 mÅ away from the line center, respectively. For ease of comparison, the negative of the red-wing magnetogram is shown. The same black or white curves are drawn to compare the locations of fine structures. The size of the selected area is 17 × 21 pixels, equivalent to 1.3 × 2.5 arcsec². The lower row shows, from left to right, profile arrays of Stokes V, linear polarization (LP = $\sqrt{Q^2+U^2}$), and Stokes I. Each Stokes profile is normalized to its own local Stokes I continuum. The pixels whose Stokes profiles are drawn are marked with small white/black square symbols in the maps of the upper row. Stokes profiles shown from bottom to top correspond to the pixels running from umbra (lower-right corner) to penumbra (upper-left corner). Three vertical dashed lines show the zero-velocity reference and ±215 mÅ around it in both spectral lines. Numerical values in the panel showing the profile array of Stokes V are the signal values (multiplied by 100) at far blue and red wings at ±215 mÅ. Also, the corresponding values of the continuum intensities are shown in the Stokes I panel. For ease of comparison, the Stokes profiles in the panels showing profile arrays are sorted with a fixed step of 0.25, 0.17, and 0.25, from the left to the right panel, respectively.
