We find that the overall width of the highest occupied band and the position of the band maximum at (π/2, π/2) agree with predictions of the t-J model and other calculations based on the Hubbard model. However, in many regions of the Brillouin zone, the shape of the band differs from these predictions. A comparison of our data with spectra previously reported on metallic samples leads to new suggestions for the phenomenology of doping.
