_exptl_crystal.density_meas_lt

Name:
'_exptl_crystal.density_meas_lt'

Definition:

   The value below 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.

Examples:

1.0 specimen floats in water

5.0 upper limit for the density (only the range within which the density lies was given in the original paper)

Type: float

Mandatory item: no

Alias:
_exptl_crystal_density_meas_lt (cif_core.dic version 2.3)
The permitted range is [0.0, infinity)
