The Sun's Image for an Aperture in the Shape of a Pythagorean Star

The shape of the aperture is quite arbitrary as said before and the Pythagorean star gives a result similar to those of the n-gons.

In the radial curves for the image the deviations for different values of the angle θ vary from a mean value and appear to be affected by the symmetry of the aperture. Both the Pythagorean star and the pentagon have five peak deviations.
