The expression for the kinematics and amplitudes of AMO
[equations (6 and 7)] are valid for
and ranging between -1 and 1. However, for finite
propagation velocities, the AMO operator has a much narrower aperture,
as shown in appendix C. Taking into account this finite aperture is
crucial both for accuracy and for efficiency. For a given minimum
propagation velocity *V*_{min}, the maximum output time can be
evaluated according to the following expressions:

To avoid truncation artifacts, we recommend the use of a tapering
function at the edges of the operator aperture.
