  • Anharmonic refinement software for single crystal data. (U.H. Zucker, E. Perenthaler, W.F. Kuhs, R. Bachmann, and H. Schulz, (1983), J. Appl.Cryst.16, 358)
  • "PROMETHEUS is designed to carry out sophisticated structure refinements using x-ray as well as neutron data. The most prominent features of the system are: Isotropic correction of thermal diffuse scattering. Absorption correction for sheres and arbitrary shaped crystals. Fast averaging of symmetrical equivalent reflections. Isotropic and anisotropic extinction correction of Zachariasen, Hamilton and Coppens, and Becker and Coppens. Refinement of anharmonic thermal tensors up to the sixth order in the Gram Charlier formalism and up to fourth order in the Edgeworth-, extended Edgeworth-, and the alpha formalism (quasi orthogonalisation formalism). Calculation and plotting of Fourier-, error-fourier-, probability-density-, and effective one particle potentials in arbitrary sections. Computation of mode- and and equilibrium positions. Calculation of Bonds and angles with standard deviations and printing of structure factor lists for publications. All programs are written in FORTRAN."
