Since the tests presented in this paper are for constant velocity, we can assume that the Jacobian weights are correct to the first order. The use of these weights is necessary to do true amplitude migration. When doing true amplitude migration, we also must keep in mind spatial and temporal sampling to reduce ``squeezing'' and aliasing effects. Also, the use of an offset ray parameter mute is necessary so that points outside of the maximum migration aperture are not used in our AVA analysis.
