The shaped reflector has approximately an elliptical projection in xy plane.
The shaped reflector has approximately an elliptical projection in plane xy and, by adding a constant to the synthesized solution L([eta]), the diameter in the symmetry plane is again adjusted to 25 cm, yielding the diameter of 29.75 cm in the asymmetry plane and the distance [r.sub.0] = 28.32 cm from O to the reflector along the ray at center of the polar grid.
Higher inaccuracy in comparison of set 3 and 4 is evoked by smaller dimensions of stones in set 4 (stones in elliptical projection occupies only approximately 13 x 9 pixels).
