+Checking the S/N values for detections in the stack CMF files (so there is no reanalysis of the images in this plot.  Only previously known objects are photometered) shows that there is an improvement in the S/N compared to the current tag:

+=== Conclusion ===
+
+I 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.
