Misorientation with respect to reference direction

Misorientation images can be calculated with respect to any direction; here, for example, the average c-axis orientation of the chipmunk is taken as the reference direction (azi=117, inc=90). Using NIH Image (or Scion Image) and the Lazy LUT macro (key M: "Misor LUT 45°=black", see appendix 2), the image is colour-coded. In this manner the misorientation of the grains surrounding the chipmunk can be observed: orientations within a 45° cone appear purple, outside the cone green.
