Name	Schema Table	Database	Description	Type	Length	Unit	Default Value	Unified Content Descriptor
gauSig	[nspid]Detection	WSA NonSurvey	RMS of axes of ellipse fit {catalogue TType keyword: Gaussian_sigma}	real	4	pixels		MORPH_PARAM
			These are derived from the three general intensity-weighted second moments. The equivalence between them and a generalised elliptical Gaussian Distribution is used to derive Gaussian sigma = (σ_a²+σ_b²)^{1/2}
grpMem	[nspid]Multiframe	WSA NonSurvey	Group membership (0=F, 1=T) {image primary HDU keyword: GRPMEM}	tinyint	1		0	CODE_MEM
grpNum	[nspid]Multiframe	WSA NonSurvey	Group number applied to all members {image primary HDU keyword: GRPNUM}	int	4		-99999999	NUMBER
gsDec	[nspid]Multiframe	WSA NonSurvey	Declination of guide star {image primary HDU keyword: GSDEC}	float	8	degrees	-0.9999995e9	POS_EQ_DEC_MAIN
gsRa	[nspid]Multiframe	WSA NonSurvey	Right ascension of guide star {image primary HDU keyword: GSRA}	float	8	hours	-0.9999995e9	POS_EQ_RA_MAIN
