_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)

May appear in list containing _exptl_crystal_id
The permitted range is 0.0 -> infinity
