Abstract
An apparatus for determining the reliability of crystallographic solutions of a specimen includes an electron beam generator, a stage for holding the specimen, an image collection system for obtaining diffraction images of crystals within the specimen, and processor for processing the diffraction images to obtain most probable indexing solutions for the crystals and to generate confidence factors associated with the most probable indexing solutions. The apparatus may utilize the confidence factors to determine the phase of the crystals within the specimen. The confidence factors may also be incorporated into reports representing the statistical confidence of various crystallographic characteristics of the specimen.
