Dispersion map along the high symmetry directions. (a) ARPES measured dispersion maps along the M-Γ-M direction at various photon energies. Nodal-line is observed to be in the vicinity of the chemical potential. (b) Dispersion maps along the high symmetry X-Γ-X direction. (c) Band dispersion along the M-X-M direction. Dirac-like state is observed. Measured photon energies are noted in the plots. Inset shows the zoomed view near the Dirac point marked with dashed white rectangular box. All the measurements were performed at the ALS beamline 4.0.3 at a temperature of 21 K. We note that, NL = nodal line, BS = bulk state, SS = surface state, DP = Dirac point.
