Rotation $\theta$, initially 83 in the $xz$ plane, is carried out first, then rotation $\phi$ about the $z$ axis. Orientation distributions 84 are described as rotations about two perpendicular axes $\delta_1$ and $\delta_2$ 85 in the frame of the cylinder itself, which when $\theta = \phi = 0$ are parallel to the $Y$ and $X$ axes. 83 to the beam line coordinates, where the beam is along the $z$ axis. 84 Rotation $\theta$, initially in the $xz$ plane, is carried out first, 85 then rotation $\phi$ about the $z$ axis.
