TABLE  udsDetection

Contains the individual UDS source detections for all science frame types in UDS including pawprint stacks, deep stacks.

This table contains the individual detections for sources originating
from multiframe images taken for the UKIDSS Ultra Deep Survey (UDS).
Where a value is derived from an SExtractor(SE) parameter that parameter
name is mentioned in brackets.
