Comparison between the magnetic field strengths from the MLR (B_MLR) and the MHD cube (B_MHD). The fields in the MHD cube are computed using Eqs. (1) and (2). The third column is the difference, B_MHD−B_MLR. The fourth column is the histogram of the difference (black curve), which is fit with a Gaussian (brown curve) and the width of the Gaussian is indicated in each case. Fifth column is same as the fourth but only over the field range where the MLR is most effective.
