…s are present The associator previously ranked candidate matches by chord distance only and accepted any pair within a fixed 1" cap, ignoring per-source and per-object positional uncertainties entirely. When the uncertainty columns are missing or contain no usable values, the score reverts to the kd-tree chord distance (the previous behavior).
The previous matcher considered only each DIASource's single nearest DIAObject. When two sources competed for the same object, the loser would be unassociated and triggered a new DIAObject even if a viable second-best candidate was nearby.
