The utility of this method in 3D is limited by the poor spatial
distribution of sources, which has also been the case with passive
interferometric methods. However, future acquisition methods may
increase source density and aperture, which could in turn produce more
useful pseudoprimaries in the crossline direction. Alternatively,
this approach could be combined with moveout operators to produce data
to add to the correlation.
