-The translation and rotation parameters of a known rigid body fragment ​with a unit cell can be determined by refining a rigid body against the known fragment. Consider the known fragment to comprise of two C atoms with sites named wC1 and wC2. Then create two more sites called C1 and C2 as follows:+The translation and rotation parameters of a known rigid body fragment ​within ​a unit cell can be determined by refining a rigid body against the known fragment.
