Fig. 8.

Histogram of the differences of the χ² normalized to the average ${\bar{χ}}^{2}$ $\bar{\chi}^2$ achieved by the MHS + ∇ ⋅ B = 0 inversion and by the MHS inversion. Color lines refer to Stokes I (red), Stokes V (blue), Stokes Q (green), Stokes U (orange), and all four Stokes parameters (black). Only pixels where B_h(log τ_c = −1.5) > 300 G are considered (see text for details).
