Attributes Summary
The area of the ellipse defined by the second moments, where the semi-major and semi-minor axes used are the HWHM (half-width at half-maximum) derived from the moments.
Major axis of the projection onto the position-position (PP) plane, computed from the intensity weighted second moment in direction of greatest elongation in the PP plane.
Minor axis of the projection onto the position-position (PP) plane, computed from the intensity weighted second moment perpendicular to the major axis in the PP plane.
