            * - :py:attr:`~ansys.stk.core.stkutil.IOrientationQuaternion.qx`
              - Get or set the first element of the vector component of the quaternion. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then QX = nx sin(A/2). Dimensionless.
            * - :py:attr:`~ansys.stk.core.stkutil.IOrientationQuaternion.qy`
              - Get or set the second element of the vector component of the quaternion. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then QY = ny sin(A/2). Dimensionless.
            * - :py:attr:`~ansys.stk.core.stkutil.IOrientationQuaternion.qz`
              - Get or set the third element of the vector component of the quaternion. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then QZ = nz sin(A/2). Dimensionless.
            * - :py:attr:`~ansys.stk.core.stkutil.IOrientationQuaternion.qs`
              - Get or set the scalar component of the quaternion. This quaternion is from the reference axes to the body frame; if n and A are the axis and angle of rotation, respectively, then QS = cos(A/2). Dimensionless.
