Sample synthetic profile with the inverted profiles and associated atmospheres. Stokes I, Q, U, and V (grey, solid lines) are shown for the 15 648.52 Å line (left panels), normalised by the average continuum intensity, along with the inverted profiles from scheme C (blue, dotted) and G (red, dashed) lines. The dashed, grey line shows the rest wavelength. The retrieved atmospheric parameters (namely T, B, γ, and v_LOS) are shown as a function of log τ_5000 Å (right panels). The stratification of the atmospheric parameters in the MHD model is also shown (grey, solid line).
