Wide-field image showing the OMC1 outflow in H₂ with proper motions of the BN object, radio source I, and radio source n superimposed. The lengths of the red-solid vectors are proportional to the motions measured by Gomez et al. (2008) with the lengths of the vectors in arcseconds equal to the motion in km s^-1 (e.g. 10′′ corresponds to a motion of 10 km s^-1). The ejection center as determined by radio proper motions is shown by a cross. The locations of the disk shadow shown in Fig. 18 and the source of the [Fe ii] jet shown in Fig. 17, V2270 Ori, are indicated.
