Top left: velocity gradient position angle as a function of the mean magnetic field position angle. The light and darker blue stripes indicate when the projected angle between the two is smaller than 20° and 10° respectively. The dashed line indicates a difference of 45° between the two position angles. Protostars are color-coded as a function of their velocity gradient, with increasing gradients as the color darkens. Top right: relation between the velocity gradient position angle andthe outflow direction. We use the same convention for the stripes and lines. We note that the blue regions indicate sources whose velocity gradient might partly be tracing the outflow motion rather than the envelope motions. Bottom: corresponding histograms of the misalignment of (left) the B field and (right) the outflow axis with respect to the velocity gradient position angle. Colors and lines delineate the same angle offsetsas in the top panels.
