  ATOMS
  	ATOMS {Integer} ...
  	Specifies the indexes of atoms defining the geometrical center
  	This keyword can be repeated and it expects a list of integers.

  TYPE
  	TYPE {Keyword}
  	Chooses the type of geometrical point
  	This keyword cannot be repeated and it expects precisely one keyword.
  	Default value: GEO_CENTER
  	List of valid keywords: FIX_POINT Defines a fixed point in space GEO_CENTER Computes the geometrical center of the listed atoms

  WEIGHTS
  	WEIGHTS {Real} ...
  	Specifies the weights for a weighted geometrical center. Default is 1/natoms for every atom
  	This keyword can be repeated and it expects a list of reals.

  XYZ
  	XYZ {Real} {Real} {Real}
  	Specifies the xyz of the fixed point (if the case)
  	This keyword cannot be repeated and it expects precisely 3 reals.
  	Default unit: [bohr]
