Torsionless pseudo-ellipse parameterisation

This model is the pseudo-ellipse model with the torsion angle set to zero, σmax = 0. The model parameters are therefore

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

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.
