Illustration of relevant angles. Angle ω measures the deviation between the magnetic field orientation (in the case of submillimeter dust polarization emission rotated by 90° from the originally detected polarization orientation) and the direction of local gravity g loc. Vector n B is the unity vector perpendicular to a measured B-field orientation along the direction of the field tension force. Angle δ is the angle between a magnetic field orientation and the intensity gradient orientation.
