Distributions of the inclination of the magnetic field for slow (black) and fast (red) components for all data sets observed closer to the disk center (μ > 0.9). “N_tc” is the number of profiles in each category where the supersonic downflow exists with a slow component. The numbers indicate the mean, the uncertainty in the mean, standard deviations, and the median values of distributions for slow (black) and fast (red) components. The vertical dotted lines mark the mode values of the distributions.
