3.3.2.2 Centroid
The Centroid Pass/Fail item allows you to define a circle that must contain the centroid of the
beam energy. To implement this test you must define the location of the center of a circle in
terms of its X and Y coordinate in the beam display window, and the Radius of the circle that
must contain it.
Both the X and Y Centroid location results will change color from GREEN to RED should the
centroid fall outside this circle.

3.3.3.1 Orientation
The Orientation Pass/Fail item applies to the major axis inclination of an Elliptical beam. The
units for these two edit controls are always in degrees. The Major axis can tilt through an angle
in the range of +90 to -90 degrees. You can set the desired tilt Angle, and a +/- Range around
this angle, that will meet your testing criteria. The Rotation result will change color from
GREEN to RED should the angle fall outside of these set limits.
