  A
  	A {Real} {Real} {Real}
  	Coordinates of the vertex A.
  	This keyword cannot be repeated and it expects precisely 3 reals.
  	Default unit: [angstrom]

  B
  	B {Real} {Real} {Real}
  	Coordinates of the vertex B.
  	This keyword cannot be repeated and it expects precisely 3 reals.
  	Default unit: [angstrom]

  C
  	C {Real} {Real} {Real}
  	Coordinates of the vertex C.
  	This keyword cannot be repeated and it expects precisely 3 reals.
  	Default unit: [angstrom]

  FREQUENCY
  	FREQUENCY {Real}
  	The frequency with which the oscillating fraction oscillates.
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 0.00000000E+000
  	Default unit: [s^-1]

  N_PRTN
  	N_PRTN {Integer} {Integer}
