Figure 3
Reorientation of a sample about the κ or φ axis of an inverse-κ system. The sample's initial position is defined in motor coordinate space by $[{{\bi t}_{{\psi _1}}}]$ . The sample is rotated about $[{\bf{d}}_\Psi ^0]$ , where $[\Psi \in \left\{ {{\rm K},\Phi } \right\}]$ , by $[{\psi _2} - {\psi _1}]$ (1). Subsequent translation to the motor position coordinates $[{{\bi t}_{{\psi _2}}}]$ restores the sample to the centre without further changing its orientation (2).
