Notes:
A reminder is given that ignoring correlations between fractional coordinates in an oblique coordinate system can lead to inaccuracies in the estimation of standard deviations of bond lengths and other derived quantities. Methods based on a paper by Templeton [Acta Cryst. (1959), 12, 771–773] are suggested to make approximate allowance for the effect when the parameter variance matrix is unavailable.
