Synthetic maps of the magnetic orientation bars, inferred from the synchrotron polarized emission, of our Galaxy seen edge-on from the position (r → ∞,ϕ = 90°,z = 0), for the six best-fit magnetic field models listed in Table 2. The left and right columns are for a halo field described by model C0 (axisymmetric) and C1 (bisymmetric), respectively, while the top, middle, and bottom rows are for a disk field described by models Ad1, Bd1, and Dd1, respectively. Each map covers a circular area of radius 15 kpc, the trace of the Galactic plane is indicated by the horizontal, red, solid line, and the rotation axis by the vertical, black, dot-dashed line. All magnetic orientation bars have the same length, and their shade of grey scales logarithmically with the polarized intensity.
