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
Derived from the maximum and minimum spatial RMS of the object profile along any direction, ie. 0.5*(A_IMAGE² + B_IMAGE²)½
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
gauSig [nspid]MapRemeasAver WSA NonSurvey Averaged RMS of axes of ellipse fit real 4 pixels   src.morph.param
gauSig [nspid]MapRemeasurement WSA NonSurvey RMS of axes of ellipse fit {catalogue TType keyword: Gaussian_sigma} real 4 pixels   src.morph.param
Derived from the maximum and minimum spatial RMS of the object profile along any direction, ie. 0.5*(A_IMAGE² + B_IMAGE²)½
