a–c ARPES measured band dispersions along \(\overline{{{{{{{{\rm{M}}}}}}}}}-\overline{{{\Gamma }}}-\overline{{{{{{{{\rm{M}}}}}}}}}\) measured using photon energies of 120, 70, and 36 eV, respectively, using LH or LV polarization as noted on each plot. d Fits of integrated EDCs (Voigt fits) taken within a momentum window of (−0.2/Å–0/Å) for 120 eV LH polarized (bottom) and LV polarized (top) data in (a) [also see Supplementary Fig. 9]. e Calculated orbital-resolved dispersion along M−Γ−M. ARPES data were collected at the ALS beamline 4.0.3 at a temperature of 260 K.
