     3=== Conclusion ===

     5I believe the unrestricted reduction is the one we accept.  There is an increase in the target PSF FWHM relative to the stricter standard reduction, although it is not significantly worse than the current analysis.  There is a gain in image depth in some areas, and that translates into higher S/N for the majority of objects.

     7The only remaining test I would like to do is to process a deep stack that has difficulties with the target PSF to determine if these changes help those stacks as well.  Optimally, if that deep stack is subjected to the excess detection bug, this deep stack test could evaluate both simultaneously.
