. Also note that Zernike terms Z
1
and Z

are not related to the original
wavefront but the tilt-corrected wavefront when the 'Cancel Average Wavefront Tilt'
option is enabled.

Zernike Fit Setup
This setup panel contains definitions of the Zernike Fit that directly influence the
wavefront representation in terms of Zernike coefficients and wavefront
reconstruction.
To open the setup panel you can use the Menu Setup Wavefront Sensor
entry or simply click right on one of the graphs on the right hand side of the main
panel. Select the tab 'Zernike Fit'.
Fit up to Zernike Order
Use this control to define the highest order of Zernike polynoms that should be used
to fit the measured wavefront within the pupil area.
