Three-dimensional mesh view of the model of the molecular envelope of V370 And, which is defined by an oblate spheroid whose equatorial plane is inclined by ∼25° with respect to the plane of the sky, attached to a biconical structure. Left: view from Earth. Right: view from the direction defined by west in the plane of the sky (the observer is on the left). The X, Y, and Z axes are represented by red, green, and blue, respectively (positive directions are in the clockwise direction). The symmetry axis of the envelope is perpendicular to the equatorial plane of the main structure (oblate spheroid).
