_diffrn_refln.class_code

Name:
_diffrn_refln.class_code

Alias:
_diffrn_refln_class_code

Definition:

   
    The code identifying the class to which this reflection has
    been assigned according to some binning strategy. This code must match a
    value of _diffrn_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 cell.
