(a)–(c) Reconstructed orientation maps for the reference layer in states S0, S1 and S2. The color maps scale red, green and blue contributions so as to span the cubic fundamental zone of orientations in Rodrigues space. (d)–(f) Maps of the confidence parameter, , corresponding to (a)–(c). (g)–(i) Kernel-averaged misorientation maps corresponding to (a)–(c). Superimposed lines indicate orientation discontinuities of ≥2°. The gray scale bar is in degrees. In all images, only voxels with are plotted.
