### x, y, z

Set the coordinates of the cluster origin.

    Example: <cluster ... x="0.0" y="0.0" z="0.0"/> (default)
    Allowed values: real (optional, coupled)

### center_x, center_y, center_z

Set the current center position for a polytope cluster. This is needed because the cluster position is defined relatively to its reference atoms, so when x,y,z and e1,e2,e3 are 0 the cluster is in its initial position. Therefore there is no relation between origin and center (unlike cell or text objects for example) and the latter must be specified.

    Example: <cluster ... center_x="0.0" center_y="0.0" center_z="0.0"/>
    (no default) Allowed values: real (optional, coupled)

### e1, e2, e3

Set the three Euler angles controlling the cluster orientation. The first rotation (e1), around the initial y axis, must be between 0 and 180 degrees. The second rotation (e2), around the initial z axis, must be between 0 and 360 degrees. The third rotation (e3), around the final z axis, must be between 0 and 360.

    Example: <cluster ... e1="0.0" e2="0.0" e3="0.0"/> (default)
    Allowed values: e1: 0.0 - 180.0, e2, e3: 0.0 - 360.0
    (optional, coupled)
