%X A method is presented whereby SILLIAC, a high-speed electronic digital computer, sums 2-dimensional Fourier syntheses for crystallographic electron-density projections of any symmetry. The trigonometrical form of a particular summation and the area over which the projection is to be calculated are determined by programme-parameters introduced with the data.
