Category DIFFRN_REFLN

Name:
'diffrn_refln'

Description:

   Data items in the DIFFRN_REFLN category record details about
   the intensities in the diffraction data set
   identified by _diffrn_refln.diffrn_id.

   The DIFFRN_REFLN data items refer to individual intensity
   measurements and must be included in looped lists.

   The DIFFRN_REFLNS data items specify the parameters that apply
   to all intensity  measurements in the particular diffraction
   data set identified by _diffrn_reflns.diffrn_id.

Example:

Example 1 - based on CAD-4 diffractometer data obtained for Yb(S-C5H4N)2(THF)4 for data set 'set1' reflection 1102.
