 Applying the MASKTESTs appears to yield a marked improvement over the previous masks, removing a number of camera feature sources of false positives.  The mask fraction is also only increased a small amount over the old masks (0.1957 static mask fraction for test30, compared to 0.1948 for test21: the reference, and 0.2380 for the previous poorly constructed MASKTESTs).
 
-Using this Test 30 dataset, we can compare these false positive reduction results against an alternate set of cuts.  The proposed cuts for retaining a detection as likely real are: IS_BAD = 0, PSF_QF > 0.85 (alternate: PSF_QF > 0.5), and a 5-sigma significance.  The following table compares these cuts against those above:

The following table compares these cuts against those above.  The cuts are added cumulatively, such that the right most column contains all cuts applied to the left.  The row labeled "Note" contains a comment about this particular set of cuts, including the PSPS ignoring proposals.  The final row shows the fraction of singly detected objects to 12x detected objects, listed as a percent.
