Free rotor pseudo-ellipse parameterisation

The free rotor model is the pseudo-ellipse model with the torsion angle restriction absent. Its parameters are

\mathfrak{M}&= \mathfrak{P}+ \mathfrak{E}+ \ma...
..._z\right\}+ \left\{ \theta_x , \theta_y \right\} ,

where Pi are the average domain position translations and rotations, Ei are the Euler angles defining the motional eigenframe, pi are the coordinates of the pivot point, and θx and θy are the maximum cone opening half-angles.
