(Left) Magnetic field vector map of NGC 3627 in the sky plane. The effective angular resolution is |${13{^{\prime \prime }_{.}}5}$|⁠. The background is the same as in figure 1. The red and blue arrows show inward and outward magnetic vectors, respectively. The vectors are plotted every 7^″. (Right) The face-on view of the magnetic field vector map, made by rotating counter-clockwise by the position angle and extending in the minor-axis direction by 1/cos i. The white circles are drawn at intervals of 1.0 kpc from the center of the galaxy. (Color online)
