The location of the metal-insulator phase boundary in the plane of interaction strength and charge transfer energy shifts by $\\sim 0.5$eV or less along the charge transfer axis, the quasiparticle weight has approximately the same magnitude and doping dependence and the qualitative characteristics of the electron-doped and hole-doped sides of the phase diagram do not change.
