Distribution of magnetic field orientations in four galactic quadrants. (Top) Map of the magnetic field orientations, where the data from Figure 2 have been divided into four quadrants (labeled I, II, III, and IV). Regions around the galactic major and minor axes have been masked out. (Bottom) Rose diagrams illustrating the magnetic field orientation distribution for each quadrant. In each plot, individual data points are scattered around the circle, and the angular distribution is shown as a gray histogram. The solid red line indicates the circular mean of the distribution.
