Example profile with its WFA estimate shown next to its the synthetic fit as returned from S1 inversions. Left and middle panels: reconstructed Stokes profiles (black, dashed line) from a pixel whose temporal and spatial location is indicated by the orange square outline in Fig. 8. Only Stokes V in this pixel had a maximum amplitude greater than σ_t. The blue, dotted line shows the minimum χ² synthetic Stokes vector produced by SIR under S1 inversions. The horizontal (dot-dashed) lines show the σ_t noise threshold for the Stokes V, while the vertical (dashed) lines denote the rest wavelengths of each spectral line. The retrieved parameters were: B = 65 G, γ = 179°, α = 0.61, v_LOS = −1.06 km s⁻¹. Right panel: Stokes I (black, dotted line) and Stokes V (blue line with markers) profile over-plotted with the WFA fit obtained from the derivative of Stokes I (orange, dashed line).
