TABLE  vhsSource

Contains merged sources from detections in vhsDetection.

Prescription for the merging (from RequiredFilters) is: Y, J, H, Ks
Bandpass Y comes from single epoch OB Y tile frame measurements.
Bandpass J comes from single epoch OB J tile frame measurements.
Bandpass H comes from single epoch OB H tile frame measurements.
Bandpass KS comes from single epoch OB Ks tile frame measurements.

Required constraints:
  • Primary key is (sourceID)
  • (frameSetID) references vhsMergeLog(frameSetID)
