| | 3 | I've been attempting to address the false positive rate, and believe part of the issue is with the v2 calculation in psphot. Disabling this appears to correct the worst issues in the y/027 stack. There is also a minimal change in the distribution of matched objects. The i/055 stack does not improve when v2 is disabled, so this is not likely to be a generic fix for all false positive issues. |
