_refine.ls_number_parameters

Name:
'_refine.ls_number_parameters'

Definition:

   The number of parameters refined in the least-squares process.
   If possible, this number should include some contribution from
   the restrained parameters. The restrained parameters are
   distinct from the constrained parameters (where one or more
   parameters are linearly dependent on the refined value of
   another). Least-squares restraints often depend on geometry or
   energy considerations and this makes their direct contribution
   to this number, and to the goodness-of-fit calculation,
   difficult to assess.
