Spectra of a spatial cut along the neutral line of Stokes V. Clockwise, starting left top: Stokes IQVU. Each subpanel shows the observed spectra in the top row, the best-fit profiles of the Gaussian inversion in the middle row, and those of the 2C inversion in the bottom row. Left to right in each subpanel: 1564.8 nm, 1565.2 nm, 630.15 nm, 630.25 nm, 630.37 nm. The x-axis (dispersion) is in mÅ, the y-axis (spatial position along the cut) in arcsec. All profiles were normalized individually to improve the visibility of the spectral patterns; the range is  ±1.
