raw_data_dislocation_A.hdf5

The file contains a dataset "data" representing the 4D-STEM measurementsof dislocation A in (0002) systematic row conditions.

Dimension #0: Scan y-axis (scale: 0.78125 nm/px)Dimension #1: Scan x-axis (scale: 0.78125 nm/px)Dimension #2: Diffraction y-axis (scale: 0.074677 nm^(-1)/px)Dimension #3: Diffraction x-axis (scale: 0.074677 nm^(-1)/px)

Please note, the diffraction coordinate system is mirrored and rotatedwith respect to the scan coordinate system.
