Name	Schema Table	Database	Description	Type	Length	Unit	Default Value	Unified Content Descriptor
gain	[nspid]MultiframeDetector	WSA NonSurvey	Detector gain {image extension keyword: GAIN}	real	4	electrons/ADU	-0.9999995e9	??
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 = (σa²+σb²)½
