Variation in the magnetic field vector components along the LOS. From top to bottom, we show the magnetic field vector component along the x, y, and z axes in the model, respectively. The different columns correspond to different positions in the FOV, whose location in normalized coordinates, P_i = (X, Z), is indicated to the left of each row. The blue curve shows the true magnetic field and the red curve the result of the inversion. The dark and light orange-shaded regions indicate the 68% and 95% confidence intervals of the inversion, respectively.
