Dust polarization map of IC 443-G at 345 GHz with half-beam sampling obtained with PolKa at the APEX telescope. The polarization level is up to 10% and the magnetic field is oriented perpendicular to the long axis of the source. All the plotted polarization vectors have p ≥ 3σ_p. The beam size is shown in the lower right corner and and the offsets are with respect to the reference coordinates , δ   (J2000) = + 22°39′36″.
