Examples of Stokes profiles from different regions in the FOV (black markers) and best fits obtained with the different methods: two-line NLTE inversions (red lines), WFA using the spectral region ±500 mÅ around the Mg line core (blue), and LTE inversion of the Fe line (green). Panels display, from top to bottom, the Stokes I, Q, U, and V profiles normalized to the average continuum intensity in the quiet Sun, I_QS. From left to right, each set of Stokes profiles corresponds to a pixel in the quiet Sun, in a bright magnetic structure, in a pore, and in a pore’s center. The resulting atmospheric stratifications are shown in Fig. 7.
