Reconstructed geometry of the η Car shell. Bottom left axis indicates distances parallel (normal) to the plane of sky. Top and right axes indicate the original measurements, as in Fig. 32, and the symbols are also the same, except that here circle size is proportional to the Hα/[N II] intensity ratio. The brown double-lobe structure near the center represents the position and actual inclination of the Homunculus Nebula (size is not to scale). The horizontal dashed line, which defines angle θ = 0, is parallel to the sky plane; the oblique line indicates the Homunculus polar axis.
