text: The eigenvectors I calculated should be orthogonal and represent the directions of the axes of the ellipsoid (and I note that these axes are not collinear with the axes of my right-handed Cartesian x, y, z (z-upward) coordinate system, thus the ellipsoid is rotated at some angle(s) to my coordinate system); the lengths of the semi-axes of the ellipsoid are computed from the eigenvalues.
