We study the Fermi surface of Bi2Sr2CaCu2O8using angle resolved photoemission spectroscopy (ARPES) with a momentum resolution of ˜0.01 of the Brillouin zone. We show that, contrary to recent suggestions, the ARPES derived Fermi surface is a large hole barrel centered at (Π, Π), independent of the incident photon energy. We caution that the photon energy and k dependence of the matrix elements, if not properly accounted for, can lead to misinterpretation of ARPES intensities.
