AmorphousFilm4nm4DSTEM |
A 4D-STEM dataset of a 4 nm amorphous thin film acquired with a 2.5 mrad probe on a Direct Electron Celeritas at 49000 fps. 256 x 256 probe positions (the central quarter of a 1024 x 1024 scan) of 128 x 128 pixel diffraction patterns. Both real and reciprocal space are calibrated - 0.12325 nm per scan step and 0.12453 1/nm per detector pixel, centred on the direct beam. Suitable for fluctuation electron microscopy and angular correlation analysis. Gain- and dark-corrected intensities were divided by 2 and rounded to uint16; multiply by 2 to recover ADU (the detector records 300 ADU per electron). |

LayeredCuNb4DSTEM |
A 4D-STEM dataset of a layered Cu/Nb nanolaminate, acquired with a nearly parallel 1.58 mrad probe on a Direct Electron Celeritas XS. 128 x 128 probe positions (the central quarter of a 512 x 512 raster scan) of 256 x 256 pixel diffraction patterns, each the sum of 32 camera frames at 25000 fps. Reciprocal space is calibrated at 0.0078768 1/Angstrom per pixel and centred on the direct beam; the detector half-width is 1.008 1/Angstrom (25.3 mrad at 200 kV). The real-space scan step was not recorded by the scan controller, so the navigation axes are in pixels. Gain- and dark-corrected intensities were divided by 2 and rounded to uint16; multiply by 2 to recover ADU. |

BilayerWS2 |
small 4-D STEM dataset of a bilayer WS2. Each Diffraction pattern is only 8x8 pixels so the dataset is quite small although for simple non iterative ptychography 8x8 pixels should be sufficient. |

ApoferritinApollo15eps |
A single cryo-EM movie of apoferritin from one stage position, collected at a 15 e-/pix/s dose rate on a Direct Electron Apollo. 76 unaligned, dark-subtracted counted super-resolution frames of 8192 x 8192 pixels at 0.2995 Angstrom per pixel, totalling 56.96 e-/Angstrom^2 (0.7495 e-/Angstrom^2 per frame). The super-resolution gain reference needed for frame correction is embedded in the file at metadata.Acquisition_instrument.TEM.Detector.gain_reference. Repackaged from EMPIAR-11254; see Peng et al., J Struct Biol X 7 (2022) 100080. |

HREBSDStrainPatterns |
High-resolution EBSD patterns collected on a Direct Electron DE-Meridian, centred on a deformed region suitable for cross-correlation strain analysis. 32 x 32 probe positions at a 25 nm step, each pattern the sum of 256 counted, dark- and gain-corrected frames, binned 2 x 2 from 2048 x 2048 to 1024 x 1024 pixels. The pattern-plane geometry (detector distance, pattern centre, sample tilt) and the accelerating voltage were not recorded with the raw data, so the pattern axes are in detector pixels. |

CuZnEELSMapping |
An EELS spectrum image of copper and zinc oxide deposited on carbon nanotubes, used by the eXSpy elemental mapping tutorial. 40 x 50 probe positions at 0.9214 nm with 162 energy channels covering 700-1988 eV at 8 eV dispersion, which resolves the Cu-L2,3 (~931 eV) and Zn-L2,3 (~1020 eV) edges. The Zn:Cu ratio is 3:1 and roughly 80 wt% of the sample is carbon, so the edges sit on a large plasmon background - a good test case for model-based background removal and overlapping-edge quantification. The simultaneously acquired survey image is available as CuZnHAADF. Note - the Sample.description field in the file reads "Ta2O5 25% TiO2 CSIRO 400C", which is stale metadata carried over from an unrelated acquisition. |

LSMOLineScan |
A core-loss EELS line scan through a La(0.7)Sr(0.3)MnO3 thin film in which part of the film was deliberately given a very long electron beam exposure, inducing oxygen vacancies. Used by the eXSpy fine structure tutorial - the O-K and Mn-L2,3 fine structure changes measurably between the damaged and undamaged regions. 40 probe positions at 3.219 nm with 586 energy channels covering 428.5-721 eV at 0.5 eV dispersion. Acquired on a JEOL ARM200cF with a Gatan Quantum ER in DualEELS mode at 80 kV, 27.42 mrad convergence and 33.19 mrad collection angle. The matching low-loss spectrum is LSMOLineScanLowLoss. |

LSMOSTOLineScan |
A core-loss EELS line scan across a La(0.7)Sr(0.3)MnO3 thin film grown on SrTiO3, used by the eXSpy perovskite oxide analysis tutorial. 10 probe positions at 3.152 nm with 512 energy channels covering 395-906 eV at 1 eV dispersion, which contains the Ti-L2,3, O-K, Mn-L2,3 and La-M4,5 edges - so a single line scan crosses the interface and shows the Ti signal give way to La and Mn. Acquired on a JEOL ARM200cF with a Gatan Quantum ER in DualEELS mode at 200 kV, 27.1 mrad convergence and 33.1 mrad collection angle. The matching low-loss spectrum needed for thickness correction and Fourier-ratio deconvolution is LSMOSTOLineScanLowLoss. Binned from the original acquisition to keep the file small. |

Acquired on a JEOL ARM200cF with a Gatan Quantum ER at 200 kV; the low-loss dwell time is 9.44e-05 s against 0.4999 s for the core loss. |
