Category cell_measurement_refln

Category Description

              Data items in the CELL_MEASUREMENT_REFLN category record
               details about the reflections used to determine the
               crystallographic cell parameters.

               The CELL_MEASUREMENT_REFLN data items would in general be used
               only for diffractometer data.
