Aurys Silinga 28/04/2025 This archive contains the code and data used to acquire the results shown the the research article "Model-Based Iterative Reconstruction of Three-Dimensional Magnetisation in a Nanowire Structure Using Electron Holographic Vector Field Tomography". 2025. Aurys Silinga, András Kovács, Stephen McVitie, Rafal E. Dunin-Borkowski, Kayla Fallon, Trevor P. Almeida. The contets of this archive are as following: "+70 saturated tilt series" Off-axis electron holography images acquired for a series of tilt angles. "double series reconstruction" Python code used to perform the magnetisation reconstruction. "empyre" The legacy version of "https://github.com/AurysSilinga/MBIR-TEM" that was used for the reconstruction. "phi 0" Pre-processed holography data from one tilt arc (at azimuthal angle 0) that was accessed by the python code. "phi 90" Pre-processed holography data from one tilt arc (at azimuthal angle 90) that was accessed by the python code. "simulations" Simulations of error functions, null spaces, and tilt range limitations used to support claims made in the article and shown in the supplementary material.
