Main and sub reflectors representations, in the global coordinate system and 2D-projections. Top row: primary reflector. Left: projection in the (x, z) plane. Center: Projection in the (x, y) plane. Right: projection in the (z, y) plane. Center row: secondary reflector. Left, center, and right are the same as in the top row. Bottom row: superposition of primary and secondary reflectors. Left, center, and right are the same as in the top row.
