Scatter plots of strength of the magnetic field (in μG) in the cone of observation versus (left) and r^TE (right), measured from the Twf (green) and Tsf (purple) galaxies for f_sky = 0.5. The strength of the field is the mass-weighed average of the field for all cells having their centers in the cone centered on the observer, with an opening angle of 60° around the z axis and with height lower than 1 kpc. Vertical and shacked lines are built the same way as in Fig. 10.
