The regular component of the GMF model in the x − y plane (parallel to the Galactic plane) as seen from above. The slices are located at vertical heights z = −3 kpc (left), z = 10 pc (middle), and z = 650 pc (right). The Sun, represented by a black dot, is located at (−8.5,0,0) kpc. The black arrows give the direction of the field along the x = y line. The magnitude of the field is color-coded and takes negative values for negative values of the azimuthal component of the field.
