Category Description

              Data items in the DIFFRN category record details about the
               diffraction data and their measurement.




Category Examples




Example 1:

    Example 1 - based on PDB entry 5HVP and laboratory records for the
                structure corresponding to PDB entry 5HVP.




    _diffrn.id                            'Set1'
    _diffrn.ambient_temp                   293.0
    _diffrn.ambient_environment
    ; Mother liquor from the reservoir of the vapor diffusion
      experiment, mounted in room air
    ;
    _diffrn.crystal_support
    ; 0.7 mm glass capillary, sealed with dental wax
    ;
    _diffrn.crystal_treatment
    ; Equilibrated in rotating anode radiation enclosure for
      18 hours prior to beginning of data collection
    ;




Example 2:

    Example 2 - based on data set TOZ of Willis, Beckwith & Tozer [(1991).
                Acta Cryst. C47, 2276-2277].




    _diffrn.id                            'd1'
    _diffrn.details
    ; \q scan width (1.0 + 0.14tan\q)\%, \q scan rate 1.2\% per
       min. Background counts for 5 sec on each side every scan.
    ;
