+I've disabled both the V2 calculation and the SOFTEN.VARIANCE parameter in the current trunk, which I believe will resolve the issues that these were causing.  This should reduce the false positive rate somewhat, particularly on stacks that have large dynamic range in the number of inputs.
+
+As a final check, Gene suggested looking at the SAVE.RESID output of psphot with the SOFTEN.VARIANCE parameter on and off to see if there are major changes in the PSF fitting.  The SOFTEN.VARIANCE=F run is on the left, =T is on the right.  There is no obvious difference.
