Describes CIF, the data exchange standard of crystallography. Provides: information for scientists who wish to record or use the results of a single-crystal or powder diffraction experiment; the data ontology necessary for designing interoperable computer applications; accompanying software including machine-readable CIF dictionaries, libraries and utility programs.
An essential guide and reference to CIF for programmers, data managers handling crystal-structure information and practising crystallographers.
The maximum and minimum transmission factors applied to the diffraction pattern measured in this experiment. These factors are also referred to as the absorption correction A or 1/A*. As this value is the one that is applied to the measured intensities, it includes the correction for absorption by the specimen mount and diffractometer as well as by the specimen itself.
