README: Experimental realization of a fermionic spin-momentum lattice. Paul Lauria, Wei-Ting Kuo, Nigel R. Cooper, and Julio T. Barreiro Physical Review Letters (2022). Folder containing all raw image data, Python analysis and processing code to exactly reproduce all data figures in the manuscript "Experimental realization of a fermionic spin-momentum lattice." METHODS The individual data files are binary ASCII absorption images as directly returned from the 16-bit camera. Their loading and use is described in the accompanying python notebooks.
