Fieldline geometrical structures of best-fit GMF models in the (x, y, z = 0) and (x, y = 0, z) planes of the Galaxy. From top-left to bottom-right: ASS, LSA, BSS, and QSS GMF models. The GMF reconstructed models corresponds to the best-fits obtained while assuming that n_d is our best-fit ED model. The black dot at the center of the figure is the Galactic center and the black star is at the Sun position. The color scales offer information about the relative strength of GMF (i.e., the norm of the vector field at each location) and of its direction (red going clockwise, blue going counter-clockwise). In the case of ASS and LSA models, the (constant) norm has been fixed to 2.1.
