| | 17 | 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). |

| | 19 | 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: |
