Item Description

The value above which the density measured using standard chemical and physical methods lies. The units are megagrams per cubic metre (grams per cubic centimetre). _exptl_crystal.density_meas_gt and _exptl_crystal.density_meas_lt should not be used to report new experimental work, for which _exptl_crystal.density_meas should be used. These items are intended for use in reporting information in existing databases and archives which would be misleading if reported under _exptl_crystal.density_meas.
