OpticalAberration

	The Optical Aberration plot is available with the Ray Optics Module.

model.result(<pgtag>).feature(<ftag>).set(property, <value>);

model.result(<pgtag>).feature(<ftag>).runCommand("createReferenceHemisphereDataset");

model.result(<pgtag>).feature(<ftag>).runCommand("recomputeReferenceHemisphereDataset");

model.result(<pgtag>).create(<ftag>,"OpticalAberration") creates an optical aberration plot feature named <ftag> belonging to the plot group <pgtag>. The optical aberration plot is used to visualize various types of monochromatic aberration. Optical aberration plots can be added to 2D plot groups.
