Metadata
The data provided below was collected by Dave Saylor while at Carnegie Mellon University. This was his dissertation project and was the first five-parameter grain boundary character distribution that was ever measured. Most of the original data is not available. The data and results below are based on crystal orientations and grain boundary plane normal vectors around roughly 19,000 triple junctions in the data set. The data was extracted from five parallel layers produced by serial sectioning (polishing). The distribution and energy results are described in the following two papers:

EBSD data
3D data
The original EBSD data is not available.
Grain Boundary line segment data
This file contains about 19,000 triple lines. For each triple line, the orientations of the three grains and the vectors normal to the three boundaries are provided

Grain Boundary Character Distribution
The is the grain boundary character distribution of MgO, calculated from the 3D data above. This is number weighted and based only on the segments that connect to triple lines. This is not expected to exactly match the original data published in 2003, but it is very close. The resolution if 9 bins per 90 degrees.

Grain Boundary Energy Distribution
The is the grain boundary energy distribution of MgO, calculated from the 3D data above. This is unsmoothed data and is not expected to exactly match what was published in 2003, but it is very close. The resolution if 9 bins per 90 degrees.
