Proposed structure of the wind derived from the data analysis in the simplified case of no rotation of the flow. Top: nested shells in the physical space (left) have progressively smaller radii, higher poloidal velocity, and faster acceleration for shells closer the axis, so that the corresponding curved surfaces in the position-position-velocity (PPV) space are progressively closer to and more inclined toward the velocity axis (right). Bottom: examples illustrating the origin of the structures seen in the orthogonal projections of the datacube.
