Abstract: The filtering program "fftfil" performs a variety of operations commonly required in geophysical studies of gravity, magnetic, and terrain data.Filtering operations are carried out in the wave number domain where the Fourier coefficients of the input data are multiplied by the response of the selected filter.Input grids can be large (2<_ number of rows or columns _<_ 1024) and are not required to have numbers of rows and columns equal to powers of two.
