TABLE  vikingSourceXDetectionBestMatch

Links each unique source in vikingSource to each tile epoch

in Multiframe (or vikingDetection).

Epochs may include a measurement (seqNum>0), but will still be linked
to epochs without measurements (seqNum==-99999999) if the frame overlaps
the source position.

Required constraints:
  • Primary key is (sourceID,multiframeID)
  • (sourceID) references vikingSource(sourceID)
  • (multiframeID,extNum,seqNum) references vikingDetectionRaw(multiframeID,extNum,seqNum)n
