ARPES studies on Sr2CuO2Cl2 and Ca2CuO2Cl2 are presented. The integrated sp
ectral weight of the low energy feature shows a drop across the AF zone bou
ndary, suggesting a remnant Fermi surface. Along the remnant Fermi surface
the dispersion fits the functional from of \cos(k(x) a) - cos(k(y) a)\ rema
rkably well. However, additional experiments with improved angular resoluti
on demonstrate that the dispersion near (pi /2, pi /2) does not contain a c
usp as would be expected from a simple d-wave theory predicting the above f
unctional form. The rounded node region and the total dispersion of approxi
mately 350meV is shown to be independent of photon energy.
