The main repository can be found https://github.com/ExpMicroMech/AstroEBSD/
Last updated: July 10, 2025 (AstroECP version)
The paper describing the basic AstroEBSD work can be found in:
Thomas Benjamin Britton, Vivian Tong, Jim Hikey, Alex Foden, and Angus Wilkinson "AstroEBSD: exploring new space in pattern indexing with methods launched from an astronomical approach" Journal of Applied Crystallography (2018) https://doi.org/10.1107/S1600576718010373 (& preprint https://arxiv.org/abs/1804.02602 )
The RTM module is presented in:

An example (large, full resolution) correlative EBSD/EDS dataset for RTM and PCA is available at https://doi.org/10.5281/zenodo.3617455. A compressed version (900 MB) is available at https://doi.org/10.5281/zenodo.3737987.
The AstroECP module is presented in:
M. Haroon Qaiser, Lukas Berners, Robin J. Scales, Tianbi Zhang, Martin Heller, Jiri Dluhos, Sandra Korte-Kerzel, and T. Ben Britton "AstroECP: towards more practical Electron Channeling Contrast Imaging" (preprint https://arxiv.org/abs/2507.00354)

Loaders of data from a few different EBSD instrument vendors are available: Bruker, TSL/EDAX, Thermo Fisher Scientific, Oxford Instrument, as well as our in-house DED-based modular stages.
