Crystal Quality, the Long and the Short of ItThe term "crystal quality" is ambiguous and implies different meanings to different crystallographers. For the physical crystallographer who aims to understand long-range aspects of crystal growth mosaicity is one of the leading measures of perfection. For the structural crystallographer and those seeking to understand growth at a short-range, molecular level, the detail in the resulting structure is a key goal. Different quality measures have been developed due to different needs. Each of the measures has advantages and each has limitations. In this talk a sample of these measures will be discussed with particular emphasis applied to their application in the analysis of microgravity grown crystals. The advantages and limitations of each will be discussed. Ultimately, the choice of crystal quality measurement lies in the nature of the question asked. It is ~scfill to remember that beauty is often in the eye of the beholder.
