'_exptl_crystal_density_meas_temp_lt 300'

;                               The density was measured as at some unspecified
temperature below room temperature.


Temperature in kelvins above which (*_gt) or below which (*_lt) _exptl_crystal_density_meas was determined. These items should not be used for reporting new work where the correct temperature of measurement should be given. They are intended for use in reporting information stored in databases or archives which would be misleading if reported under _exptl_crystal_density_meas_temp.
