Top panels: map of Stokes V integrated over the blue-shifted wings of the CO (J = 2 → 1) emission in IC 443-G (left) and the corresponding 0° to 90° distribution of the phase-shift φ between the orthogonally polarized radiation components of CO (J = 2 → 1) averaged over the same velocity ranges as Stokes V (right). Bottom panels: same as above but for CO (J = 1 → 0). The beam sizes are shown in the lower right corners and the offsets are with respect to the reference coordinates , δ   (J2000) = + 22°39′36″.
