ARPES constant energy map near Fermi level given in analyzer angle - polar angle units that was obtained by stitching together many energy - analyzer angle maps with polar angle motion perpendicular to the direction of analyzer's angular dispersion/slit. Sample was also tilted from normal emission by 18 degrees. Parts of the band structure repeated in neighboring Brillouin zones are also visible.
