3D view of the OMC-1 outflow from the expansion center  ≤ 720 years ago to the present time. The blue dot is the computed expansion center (α_J2000 = 05^h35^m1450, δ_J2000 =  −05°22′2300). Yellow, green and turquoise points show the disposition of the Peak 1, Peak 2 and Region B objects through time. The snapshots are at intervals of 40 years. xy is the plane of the sky. Notwithstanding the magnetic deflection model introduced in Sect. 5, we have for simplicity and to avoid model dependence used rectilinear trajectories in this and all other relevant figures.
