+Chosing a 216 atom supercell constitutes a tradeoff, of course.
+However, it is considered the optimal choice with respect to both,
+computing time and accuracy of the results.
+
+The convergence of the formation energies of single defects with
+respect to the size of the supercell is ensured. For this reason, they
+are reffered to as single isolated defects.
+
+It is not our purpose to separate defects by a large distance in order
+to approximate the situation of isolated defects. However, we find
+that for increasing defect distance configurations appear, which
+converge to the energetics of two isolated defects. This is indicated
+by the (absolute value of the) binding energy, which is approaching
+zero with increasing distance. From this, we conclude a decrease in
+interaction, which is already observable for defect separation
+distances accessible in our simulations. This is stated in the text
+already in the early beginning of section III B.
+
+Nevertheless, the focus is on closely neighbored, interacting defects
+(for which an interaction with their own image is, therefore, supposed
+to be neglectable small, too). At no time, our aime was to investigate
+single isolated defect structures and their properties by increasing
+the separation distance of two defects belonging to a a defect
+combination.
+
+A note is added to let the reader know that convergence with respect
+to the system size is ensured. (-> Change 2)
