Simulated images of the total flux density in K_s band (first panels from the left side), linearly polarized flux density (second panels from the left side), the distribution of the polarization degree (second panels from the right side), and the distribution of the polarization angle (first panels from the right side) for the different position angle of the bipolar outflow; δ = 0°, 45°, and 90°from the top to the bottom panels.
