Free rotor pseudo-ellipse parameterisation

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

$\begin{subequations}\begin{align} \mathfrak{M}&= \mathfrak{P}+ \mathfrak{E}+ \ma... ..._z\right\}+ \left\{ \theta_x , \theta_y \right\} , \end{align}\end{subequations}$

where P_i are the average domain position translations and rotations, E_i are the Euler angles defining the motional eigenframe, p_i are the coordinates of the pivot point, and θ_x and θ_y are the maximum cone opening half-angles.
