Category REFLNS



   Data items in the REFLNS category record details about the
   reflection data 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.


Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP.
    _reflns.entry_id                       '5HVP'
    ; Xengen program scalei. Anomalous pairs were merged. Scaling
      proceeded in several passes, beginning with 1-parameter
      fit and ending with 3-parameter fit.
    ; Merging and scaling based on only those reflections
      with I > \s(I).
