               sample is prepared.

    _type                        char
    _definition
;              A description of how the material was prepared
               (reaction conditions, etc.)

    _units_detail               'kelvins/minute'
    _definition
;              Cooling rate in kelvins per minute for samples prepared
               at high temperatures. If the cooling rate is not linear
               or is unknown (e.g. quenched samples), it should be
               described instead in _pd_prep_conditions.

    _units_detail               'kilopascals'
    _definition
;              Preparation pressure of the sample in kilopascals. This
               is particularly important for materials which are metastable
               at the measurement pressure, _diffrn_ambient_pressure.

    _units_detail               'kelvin'
    _definition
;              Preparation temperature in kelvins of the sample. This is
               particularly important for materials which are metastable
               at the measurement temperature, _diffrn_ambient_temperature.
