Figure 10.

(a) Zone-plate and (b) square torus representations of the combined orientations from three EBSD scans (7 039 154 scan points in total) of a polycrystalline forsterite sample with random texture. The small white dot in the upper right portion of the RFZ outline represents the projection of the mean orientation quaternion μ for a Watson distribution fit to the orientation set (see text). The circled area in panel (b) highlights a cluster of higher intensity. (Data sets courtesy K. Marquardt, University of Oxford.)
