Category diffrn_reflns_class

Category Description

              Data items in the DIFFRN_REFLNS_CLASS category record details
               about the classes of reflections measured in the diffraction
               experiment.




Category Examples




Example 1:

    Example 1 - example corresponding to the one-dimensional incommensurately
                modulated structure of K~2~SeO~4~. Each reflection class is
                defined by the number m=sum|m~i~|, where the m~i~ are the
                integer coefficients that, in addition to h,k,l, index the
                corresponding diffraction vector in the basis defined for
                the reciprocal lattice.
