We continue the work of Vlad et al. (2003) on implementing
the Zhang amplitude corrections for wavefield extrapolation
imaging. We apply the corrections to the case of propagation through a less
particular *v*(*x*,*z*) velocity model than the one used in the previous
paper. The corrections result in an increase in wavefield
focusing. We apply with encouraging results the boundary
condition correction to the linearized downward continuation used in
wave-equation migration velocity analysis. The propagation operator
correction, however, is not applicable to linearized downward
continuation.
