Name:
'_refine_ls_number_restraints'

Definition:

   The number of restrained parameters. These are parameters which
   are not directly dependent on another refined parameter.
   Restrained parameters often involve geometry or energy
   dependencies.
   See also _atom_site_constraints and _atom_site_refinement_flags.
   A general description of refinement constraints may appear in
   _refine_special_details.


The permitted range is 0 -> infinity
