Name	Schema Table	Database	Description	Type	Length	Unit	Default Value	Unified Content Descriptor
imageExtent	[nspid]CurrentAstrometry, [nspid]PreviousAstrometry	WSA NonSurvey	The maximum angular extent from the central position	real	4	Arcminutes		POS_ANG_DIST_GENERAL
imageExtName	[nspid]MultiframeDetector	WSA NonSurvey	Extension name in source FITS image file {image extension keyword: XTENSION}	varchar	16		NONE	??
imageGcount	[nspid]MultiframeDetector	WSA NonSurvey	FITS image extension required keyword (always 1 for uncompressed images) {image extension keyword: GCOUNT}	int	4			NUMBER
imagePcount	[nspid]MultiframeDetector	WSA NonSurvey	FITS image extension required keyword (always 0 for uncompressed images) {image extension keyword: PCOUNT}	int	4			NUMBER
imagesLocation	[nspid]ExternalSurvey	WSA NonSurvey	Pathname to the pixels (eg. for list-driven remeasurement)	varchar	256			??
isoFlux	[nspid]Detection	WSA NonSurvey	Instrumental isophotal flux counts {catalogue TType keyword: Isophotal_flux}	real	4	ADU		PHOT_INTENSITY_ADU
			Standard definition of summed flux within detection isophote, apart from detection filter is used to define pixel connectivity and hence which pixels to include. This helps to reduce edge effects for all isophotally derived parameters.
isoMag	[nspid]Detection	WSA NonSurvey	Calibrated isophotal magnitude	real	4	mag		PHOT_INT-MAG
