The planar reversal model. (a) A cross section along the x–y plane with the positive x-axis toward the Galactic center, located at (8.15, 0, 0) kpc. The green line indicates the orientation of the reversal, with a clockwise field (blue arrows) on the near side, and counterclockwise field (red arrows) on the far side. (b) The reversal model in three-dimensional space. The reversal is depicted as a diagonal plane separating a region with a clockwise field (blue arrows) below and a counterclockwise field (red arrows) above. The blue to yellow plane colors reflect the z-values to enhance three-dimensional visualization. The position of the Sun is shown by ⊙.
