Name:
'_restr_U_rigid_target_weight_param'

Definition:

   The weighting parameter = sqrt(1/weight).
   The expectation value of the difference between the components
   of the atomic displacement parameter, U,
   along the bond direction of the two atoms that define the bond.
   This number is used to assign a weight during refinement.
   A value of zero causes the restraint to become a constraint.
   This item has a default value of zero.
