Comparison of the ideal surface to two polynomial expansions. (a) Ideal paraboloid, computed for q = 4 m, θ = 5 mrad. (b) Point-by-point comparison with a series expansion up to (i + j) ≤ 4. (c) Comparison with a series expansion up to (i + j) ≤ 6. Note that the rendering of the domain is not isometric.
