Dataset for the article "Uncovering surface states of the Dirac semimetal BaMg2Bi2"

ARPES data for the manuscript "Uncovering surface states of the Dirac semimetal BaMg2Bi2" by De Vita et al. Data are in .txt format, exported from Igor Pro, and include the correct binding energy and wavevector scaling. The dataset is divided in two files; each file stores data of one k-space direction, either parallel to Γ-K or parallel to Γ-M. Within each file, labels identify (E, k) spectra acquired with a certain photon energy or light polarization: Photon energies span the range from 75 eV to 115 eV in steps of 5 eV. The light polarization is either linear vertical (LV), i.e., with the polarization vector completely in the plane of the sample surface, or linear horizontal (LH), i.e., with a component of the polarization vector partly out of the sample surface plane. For example, LH_75eV identifies the (E, k) spectrum acquired at 75 eV photon energy with linear horizontal light polarization. Further details on samples can be found in the related article.
