Presence of the contribution from 3B_{1g}- states at other k- area means the two-channel processes of scattering. As consequence, the method of integration with a constant energy interval reproduces not only remnant Fermi surface at least, but one of the contributions of above states to the total spectral intensity9 pages, 3 figuresStrongly Correlated Electronstext
