Abstract : Techniques for the computer-assisted evaluation of crystallographic data have been developed to improve the data compilations of the NBS Crystal Data Center and the JCPDS--International Centre for Diffraction Data. The resulting computer program, NBS*AIDS80, can be used for the analysis of unit-cell and powder diffraction data by the general scientific community as well. Research and analysis components include calculation of standard cells and space groups, determination of metric symmetry, checking the data for consistency, generation of d-spacings and indices, and analysis of powder patterns with calculation of figures of merit. Detailed input and output specifications are given.
