Inversion results for regions A (upper tile) and B (lower tile). Left panels (from top to bottom): Observed (black dots) and inverted (red solid lines) I/I_c, Q/I, U/I, and V/I profiles at μ = 0.43. Right panels (from top to bottom): Two-node fitted vertical bulk velocities and three-node fitted magnetic field components B_∥, B_⊥, and ϕ_B⊥. As a reference, we also show the Stokes profiles obtained in the absence of bulk velocity and magnetic fields (orange dashed lines). In addition, we included the synthetic Stokes profiles obtained for the inferred magnetic field stratification after switching off the magnetic field one node at a time (deepest to highest, corresponding to the magenta, green, and blue solid lines, respectively).
