pupil size and position.
Use this panel with activated option 'Show Pupil' for interactive beam alignment to
the Wavefront Sensor. Only the spots detected within the pupil will contribute to
the calculation of the Zernike fit.
Note: The ' Use Beam Centroid ' option needs to be activated in the
Pupil Definitions Setup panel to show the actual beam centroid.
Align the beam so that the center cross of the pupil coincides with the center
image axis.

Beam View Panel
The Beam View panel gives you an overview about the intensity distribution within
the active camera sensor area. This display is comparable to that of a camera
based Beam Profiler, but with the constraint of very poor resolution.
The lateral resolution is not determined by the camera pixel size like in case of a
real Beam Profiler, but rather given by the pitch of the lenslet array. One point of
the displayed intensity array is derived from the calculated mean intensity of the
corresponding spot.
