Category Description
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.
Local Description Enter the details about the crystallographically unique set of measured reflection data used to determine the coordinates of this deposition.Note that the collection characteristics entered here may be different from the values which are to be entered under 'Refinement Statistics'.
Category Examples 
Example 1:
Example 1 - based on PDB entry 5HVP and laboratory records for the
structure corresponding to PDB entry 5HVP
_reflns.entry_id '5HVP'
_reflns.data_reduction_method
; Xengen program scalei. Anomalous pairs were merged. Scaling proceeded
in several passes, beginning with 1-parameter fit and ending with
3-parameter fit.
;
_reflns.data_reduction_details
; Merging and scaling based on only those reflections with I > \s(I).
