Geometry of the magnetic field vector in the NE region. Black dots, triangles, and squares indicate the sky-projected orientation (lower panel) and inclination (upper panel) of the magnetic field in relation to the water masers belonging to the NE-1, NE-2, and NE-3 streamlines, respectively, assuming that the magnetic field lines coincide with the maser streamlines. The inclination angle of the jet axis with the plane of the sky is taken to be 15°. In the upper panel, the blue symbols with error bars give the value and corresponding uncertainty in the magnetic field inclination from the maser polarization fit (see Table 1). The two black dashed lines mark the inclinations of 45° and 65°. In the lower panel, colored symbols with error bars denote the determined magnetic field orientation, using blue or red colors if the LOS inclination of the magnetic field is lower or higher than 55°, respectively. Masers are identified using the same label numbers as in Table 1.
