Annotator input notes
Indexed 4D-STEM nanobeam diffraction dataset
The input represents a 21 by 17 scan with 20 nm spacing. Six indexed diffraction vectors were retained at every scan position. diffraction_peaks.csv contains detector-coordinate q vectors, scan coordinates, h/k indices, integrated intensity and peak-position uncertainty; it contains no strain, hotspot or exclusion label.
detector_calibration_peaks.csv contains an independent diffraction standard measured in the same detector geometry, with raw and certified reciprocal vectors. The calibration includes scale, shear, rotation-like cross terms and beam-center offset. reference_reciprocal_lattice.csv gives the unstrained reciprocal basis in sample coordinates. roi_definitions.csv specifies reporting regions only.
All q values are in nm-1 and use column vectors. The reciprocal/real-space convention, polar-strain definition, line-profile position and public QC limits are in analysis_config.json. Principal directions are axial, so 0 and 180 degrees are equivalent.
The records are physics-based synthetic 4D-STEM peak lists generated from a smooth elastic strain/rotation field, reciprocal-lattice inverse-transpose kinematics, detector affine distortion and nonzero peak-position/intensity noise. They contain no private sample, facility or personnel data.
