+The check of remaining residual detection patterns suggested that the magnitude limit was not set correctly.  I reran the test with a different limit:
+
+|| Reduction || All N=1|| All N=12 || Good flags N=1 || Good flags N=12 || QF Perfect N=1 || QF Perfect N=12 || 5-sigma N=1 || 5-sigma N = 12 ||
+|| Test 21   || 145775 || 406873   || 108120         || 397013          || 45890          || 383864          || 13309       || 377687         ||

+
+Matching the test21 results against SDSS, and applying the same cuts as above yield the following results:
+
+|| Reduction || All N=1|| All N=12 || Good flags N=1 || Good flags N=12 || QF Perfect N=1 || QF Perfect N=12 || 5-sigma N=1 || 5-sigma N = 12 ||
+|| Test 21 SDSS match   ||  11252  || 351886 || 10654 || 344675 || 8743 || 333924 || 1477 || 328491 ||
+|| Test 21 SDSS unmatch || 114056  || 7092   || 81312 || 6024   || 30599|| 5718   || 9296 || 5575   ||
+
+The following plots show the only the objects that are unmatched in SDSS, as these are remaining false detections.
