   Data items in the REFLNS category record details about the
   reflections used to determine the ATOM_SITE data items.

   The REFLN data items refer to individual reflections and must
   be included in looped lists.

   The REFLNS data items specify the parameters that apply to all
   reflections. The REFLNS data items are not looped.
