Category DIFFRN_MEASUREMENT

Name:
'diffrn_measurement'

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.
 
    _diffrn_measurement.diffrn_id          'd1'
    _diffrn_measurement.device             '3-circle camera'
    _diffrn_measurement.device_type        'Supper model x'
    _diffrn_measurement.device_details     'none'
    _diffrn_measurement.method             'omega scan'
    _diffrn_measurement.details
    ; 440 frames, 0.20 degrees, 150 sec, detector distance 12 cm, detector
      angle 22.5 degrees
    ;



Example 2 - based on data set TOZ of Willis, Beckwith & Tozer [Acta Cryst. (1991), C47, 2276-2277].
 
    _diffrn_measurement.diffrn_id       's1'
    _diffrn_measurement.device_type     'Philips PW1100/20 diffractometer'
    _diffrn_measurement.method          'theta/2theta (\q/2\q)'
