Profile examples showing the observed spectra (black crosses), the best-fit of the 2C inversion (blue line), and the best-fit of the Gaussian inversion (red line). In each panel, Stokes IQUV are shown from left to right, and the lines 1564.8 nm, 1565.2 nm, 630.15 nm, 630.25 nm, and 630.37 nm from bottom to top. The locations of the profiles inside the FOV are marked by crosses in Fig. 1.
