+      Transition area.
+      The idea behind this parametrization is that:
+      one glass module with its wrap is always
+      a size of 4 crystal modules with its wraps.
+      Then the transition area (where glass meets crystals) has no gaps

+        GlassModule_sx = 2*CrystalModule_sx
+        GlassModule_sy = 2*CrystalModule_sy
