_refln.class_code

Name:
'_refln.class_code'

Definition:

   The code identifying the class to which this reflection has been
   assigned. This code must match a value of _reflns_class.code.
   Reflections may be grouped into classes for a variety of
   purposes. For example, for modulated structures each reflection
   class may be 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.
