Comparison between the physical parameters obtained through M-E inversion codes: magnetic field strength B (top row), inclination of the magnetic field vector with respect to the observer’s line-of-sight γ (middle row), and line-of-sight velocity v_los (bottom row). The comparison between the ASP/HAO code and VFISV is displayed in the left column, while VFISV-HeLIx⁺and HeLIx⁺-ASP/HAO are compared on the middle and right columns, respectively. The color scale indicates a logarithmic density plot, where red regions contain about 3000 points from Fig. 1.
