_atom_site_disorder_assembly

Name:
'_atom_site_disorder_assembly'

Definition:

   A code which identifies a cluster of atoms that show long-range
   positional disorder but are locally ordered. Within each such
   cluster of atoms, _atom_site_disorder_group is used to identify
   the sites that are simultaneously occupied. This field is only
   needed if there is more than one cluster of disordered atoms
   showing independent local order.

Examples:

A disordered methyl assembly with groups 1 and 2
B disordered sites related by a mirror
S disordered sites independent of symmetry
