ARPES constant energy map near Fermi level given in crystal momentum 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 AND transforming the map from three angular to two momentum channels. Sample was tilted from normal emission by 18 degrees. Parts of the band structure repeated in neighboring Brillouin zones are also visible.
