Description:
        Data items in the DIFFRN_MEASUREMENT category record details
               about the device used to orient and/or position the crystal
               during data measurement and the manner in which the
               diffraction data were measured.
Examples:| Example 1 - based on PDB entry 5HVP and laboratory records for the
                 structure corresponding to PDB entry 5HVP
