Category struct_ncs_oper

Category Description

              Data items in the STRUCT_NCS_OPER category describe the
               non-crystallographic symmetry operations.

               Each operator is specified as a matrix and a subsequent
               translation vector. Operators need not represent proper
               rotations.
