  	Default unit: [s^-1]

  INTERCEPT
  	INTERCEPT {Real}
  	The intercept of the rectangle's plane.

  	Default unit: [angstrom]

  N_PRTN
  	N_PRTN {Integer} {Integer}
  	The number of partitions in the directions of the unit vectors generating the corresponding PARALLEL_PLANE (e1, e2 or e3) for tiling the rectangluar region.
  	This keyword cannot be repeated and it expects precisely 2 integers.
  	Default values: 1 1

  OSCILLATING_FRACTION
  	OSCILLATING_FRACTION {Real}
  	A fraction of the field can be set to oscilate over time.
