Figure 4
The sample rotation angles ωs, χs and φs change the perspective on the pole figure coverage (and fixed sample inside the instrument). The scattering vectors in the pole figure coverage plot, representing the diffraction vectors for each detector panel, should rotate in the opposite sense of the sample rotation angles. With this understanding we can track the asymmetric features in MAUD (vent, indicated by red circle, and door, the large gap in the coverage) and verify that the coordinate system transformation calculated by MAUD agrees with the definition of rotations (see text). The coverage plots and corresponding viewpoints of the HIPPO instrument and sample holder are shown for changing ωs, χs and φs individually as indicated. The sample coordinate system, in which the pole figures are defined, remains constant as defined in the text. Note that the diffraction vectors in the southern hemisphere are plotted as antipodes. |
