Name	Schema Table	Database	Description	Type	Length	Unit	Default Value	Unified Content Descriptor
object	Multiframe	WSA	Object name from telescope {image primary HDU keyword: OBJECT}	varchar	64		NONE	ID_TARGET

objID	CompleteStars, ReliableGalaxies, ReliableStars, Source	SSA	Unique identifier of merged source	bigint	8			ID_MAIN
objID	Detection	SSA	Unique object identification number	bigint	8			ID_MAIN
objID	JunkDetection	SSA	Unique object identification number from Detection	bigint	8			ID_MAIN
objID	dxsListRemeasurement, gcsListRemeasurement, gpsListRemeasurement, lasListRemeasurement, UKIDSSDetection, udsListRemeasurement	WSA	Unique identifier for this detection, or default for no detection	bigint	8		-99999999	ID_MAIN
objID	dxsDetection, gcsDetection, gpsDetection, lasDetection, udsDetection	WSA	Unique identifier for this detection, or default for no detection	bigint	8		-99999999	ID_MAIN
			This attribute is included to provide a single identification number for real detection rows (objID>0) when making cross-neighbour tables between source and detection. In general, users should NOT use this attribute for look-ups between the source and detection tables, because every detector frame has a default row in the detection table, so there are many, many thousands of rows with objID=-99999999 in each detection table which will be associated with every look-up of objID=-99999999 from source (i.e. those rows for which there is no detection or no frame in a particular passband). See the glossary entry for objID in source tables for more information.
