Results of 2D inversions applied to simulations; test of node position in Sim 1 when the top node is placed at log τ = −1.5 (left column), log τ = −2.0 (middle column), and log τ = −2.5 (right column). Two-dimensional histograms of the difference of the original smeared and inverted quantities: magnetic field (top), LOS velocity (middle), and inclination (bottom) as a function of optical depth. The mean difference is indicated by solid lines and the standard deviation of the scatter is indicated by the dashed.
