FOUR: A general crystallographic Fourier program
Abstract
FOUR computes two and three dimensional Patterson and electron density maps for crystallographic data with any space group symmetry. The program utilizes regular Fourier techniques for the summations in sections and down a given page. The final summation across the page is computed by use of a fast Fourier transform algorithm. A detailed description of the program together with the symbolic program listing is supplied.
