(submitted) and contains data on the density of dislocations and their stress fields in olivine rocks deformed via laboratory experiments. The data were used to investigate how the quality of diffraction patterns obtained via electron backscatter diffraction (EBSD) affect the stress maps and geometrically necessary dislocation (GND) maps obtained via analysis with high-angular resolution electron backscatter diffraction (HR-EBSD). These results can be used to optimize the patterns collected during EBSD to reduce noise in the HR-EBSD analysis.

Data are provided in a zip folder and include:

• Measurements of lattice orientation via EBSD: six raw .ctf files and six processed .ctf files of regions mapped with HR-EBSD
• Examples of electron backscatter diffraction patterns used to calculate radial power spectra: 12 .tiff files of diffraction patterns
• Densities of geometrically necessary dislocations from the HR-EBSD analysis: six .txt files of processed data
• Residual stress heterogeneity also determined from HR-EBSD analysis: six .txt files of processed data

Data types and the number of frames averaged are also indicated in the file names. Files are organized into folders by the number of frames averaged. A full description is available in the data description file.
