    • The variational energy weakly depends on a, c and d, but has a relatively narrow minimum as a function of b. Thus, the position of the Gaussian peaks has a special significance.

    • Thus, if the parameters of the Gaussian are optimized for hole-doped cases, it is probable that the position of the Gaussian peak smoothly approaches (π 0), as |δ| becomes large.
