-% We would like to remind the referee that the properties of isolated,
-% non-intertacting defects were modeled in separate simulation runs. It
-% is not our purpose to separate defects by a large distance in order to
-% approximate the situation of isolated defects. We are rather
-% interested in interacting defects. However, we did find that for
-% increasing defect distances, 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. Combinations of defects with
-% similar distances were already successfully modeled in a supercell
-% containing 216 atoms as described in PRB 66, 195214 (2002).
