Complete SOFIA/HAWC+ band D (154 μm, left) and E (214 μm, right) polarization maps of OMC-3. The total intensity is shown with overlaid polarization vectors in blue. The length of the vectors is proportional to the polarization degree and the direction gives the orientation of the linear polarization. The isocontour lines mark 20, 40, 60, and 80% of the maximum intensity. According to criteria (2) and (3) only vectors with I > 100 σ_I and p > 3 σ_p are considered (see Sect. 2). The beam size of 13.6″ for band D and 18.2″ for band E (defined by the FWHM) are indicated on the lower-right.
