This zipped file contains two sets of 3D angle-resolved photoemission (ARPES) maps obtained at the Spectromicroscopy beamline of the Elettra synchrotron. Each of these constructs a 3D ARPES data cube used to produce the sections of the PdSe2 band structure shown in Figures 2, 3, and 5 of the paper. The format and structure of the files requires proprietary software of the Spectromicroscopy beamline to read and analyse; please contact the corresponding authors of the paper to discuss this.
