SiO line polarization results in the blueshifted component of the HH 211 jet in two wide-velocity channels. The velocity ranges are indicated in the upper left corners. The asterisk marks the position of the central driving source. Contours show the intensity of the SiO emission. They start from 30σ with a step of 60σ, where σ ~ 0.85 mJy per beam, which is the noise level of polarized emission. Line segments show the polarization orientations (E vectors), with their length indicating the polarization degree. They are color coded according to their S/N ratio in polarized intensity
