General shape of the molecular lobes in our 3D reconstruction. The outer shells are represented by meshes viewed from four angles. The front view is that for a terrestrial observer but, for convenience, rotated by a position angle of –17°. The northern lobe is shown with a white mesh, southern with a blue one. Cartesian xyz axes are shown for reference in red, green, and blue, respectively. The blue axis corresponds to the line of sight. The convention of counting the azimuthal (θ) and polar (ϕ) angles is shown in the inset. Each lobe is ~8′′ long.
