Category Description
Data items in the DIFFRN_REFLNS category record details about
the set of intensities measured in the diffraction experiment.
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 a diffraction data set.
