 small angle diffraction situations there may be a number of closely similar "best fits",
 so some trial and error, or fixing of some radii at expected values, may help.

 To provide easy access to the orientation of the triaxial ellipsoid,
 we define the axis of the cylinder using the angles $\theta$, $\phi$
