Fourier Transform Operations

There are Fourier transform operations for both 1D and 2D applications in the SU package. The 1D transforms provide spectral (either amplitude or phase) information about each trace in a panel of seismic data.

The 2D transforms include the seismic F-K variety, assuming that the fast dimension of the input data is temporal, and the second dimension is spatial, and the non-seismic K1-K2 variety, in which the input is assumed to be purely spatial (x1,x2) data.
