Detailed description of the data product
========================================
.. DetailedDescStart

An XML data product containing a FITS catalog of Zernike amplitudes in the detection region - either the same detectors 
or quadrants for multiple exposures used in PSF phase diversity calibration of PSF fitting. The same stars
will be fit in multiple exposures to increase signal-to-noise. The Zernike modes are determined by the type
of fitting and configuration.
