Scatter plots of strength of the local magnetic field (in μG) versus (left) and r^TE, measured from the Twf (green) and Tsf (purple) galaxies for f_sky = 0.7. The strength of the field is the volume-weighed average of the field of all cells having their centers within a sphere radius of 500 pc centered on the observer. Gray and red vertical lines are the same as in Fig. 8. The gray tine solid line show the medians of the data points and the shacked black lines show running means along |B | considering 10 data points at a time.
