Cross sections of the ODs of the model perpendicular to a twofold perpendicular-space direction. (a) B OD, consisting of a hollow center B1, a second shell B2 generating Yb positions (red) and a third shell B3 generating Cd positions (blue). The center and the third shell are truncated along the fivefold (5f⊥) directions. (b) V OD, consisting of a hollow center V1 plus a second and third shell, V2 and V3, generating Cd positions (blue). The outer shells B3 and V3 include regions (light blue) along the twofold (2f⊥) and threefold (3f⊥) directions, respectively, generating positions subjected to physical-space shifts (see text). (c) E OD with ellipsoidal shape generating Cd positions. The short axis is parallel to a fivefold direction.
