The overall calculation scheme. (a) The steps used to calculate parameters common to all targets. The letters a–f from top to bottom refer to the steps for calculating the target described in §3. The same steps in the direction from bottom to top refer to the steps for calculating the derivatives described in §4. The steps are applied independently to each atomic group required to be planar. (b) The particular parallelity targets that can be constructed on the basis of the calculated parameters of an atomic group. |
