Small set of field lines for each of our four models of spiraling, possibly X-shape magnetic fields in galactic halos, as seen from an oblique angle. The shapes of field lines for the three halo-field models A1, B, and D are also representative of our three disk-field models Ad1, Bd, and Dd. All the plotted field lines lie on the same winding surface (Eq. (26) with ϕ_∞ = 0° and g_ϕ(r,z) given by Eq. (23) with p₀ = −9°, H_p = 1.5 kpc, and L_p = 45 kpc), and their footpoints, (r₁,ϕ₁,z₁), on the relevant reference surface (r = r₁ in models A1 and B, and z = z₁ in models C and D) are given by: a)(3 kpc,172°,0.5 kpc) and (3 kpc,357°,2 kpc) in model A1 (with a = 0.05 kpc^-2); b)(3 kpc,326°,1 kpc), (3 kpc,357°,2 kpc), and (3 kpc,198°,3 kpc) in model B (with n = 2); c)(2.5 kpc,336°,0) and (7.5 kpc,318°,0) in model C (with a = 0.01 kpc^-2); and d)(2.5 kpc,168°,1.5 kpc), (5 kpc,47°,1.5 kpc), and (7.5 kpc,339°,1.5 kpc) in model D (with n = 0.5). The galactic plane is represented by the red, solid circle of radius 15 kpc, and the rotation axis by the vertical, black, dot-dashed line.
