Category DIFFRN_REFLNS_CLASS

Name:
'diffrn_reflns_class'

Description:

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

Example:

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.
