Name:
'DIFFRN_REFLN'

Parent category:
DIFFRN

Definition:

   
    Data items in the DIFFRN_REFLN category record details about
    the intensities measured in the diffraction experiment,
    prior to data reduction and merging.

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

    (Data items in the DIFFRN_REFLNS category specify the parameters
    that apply to all intensity measurements.)

Category is of type Loop
