Example of the observed (after PCA deconvolution; filled circles) and best-fit (solid lines) Stokes profiles resulting from the inversion (see Sect. 4.3) in a intraspinal pixel. From top to bottom: results for I, Q, U, and V. From left to right: results for Fe I 1565.85 nm, Fe I 1565.28 nm, and Fe I 1566.20 nm (see Table 1). The location of this particular pixel is indicated in Fig. 8 with a black square.
