  ORIG_IS_VIRTUAL
  	ORIG_IS_VIRTUAL {Logical}
  	The original MO (x) is a LUMO.
  	This keyword cannot be repeated and it expects precisely one logical.

  ORIG_MARKED_STATE
  	ORIG_MARKED_STATE {Integer}
  	Specifies the MO according to the marks set in MOLECULAR_STATES. The value corresponds to the repetition of MARK_STATES in MOLECULAR_STATES
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 0

  ORIG_MO_INDEX
  	ORIG_MO_INDEX {Integer}
  	Index of the original MO (x). Counting down in energy with HOMO=1 or up from LUMO=1, depending on ORIG_IS_VIRTUAL.
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 0

  ORIG_SCALE
  	ORIG_SCALE {Real}
  	Scaling factor of the result variable (b).
  	This keyword cannot be repeated and it expects precisely one real.

  ORIG_SPIN_INDEX
  	ORIG_SPIN_INDEX {Keyword}
  	Spin of the MO (x) to be modified.
  	This keyword cannot be repeated and it expects precisely one keyword.
  	Default value: ALPHA
  	List of valid keywords: ALPHA Majority spin BETA Minority spin

  RESULT_MARKED_STATE
  	RESULT_MARKED_STATE {Integer}
  	Specifies the MO according to the marks set in MOLECULAR_STATES. The value corresponds to the repetition of MARK_STATES in MOLECULAR_STATES
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 0

  RESULT_MO_INDEX
  	RESULT_MO_INDEX {Integer}
  	Index of the MO (y) to be modified. Counting down in energy with HOMO=1
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 0

  RESULT_SCALE
  	RESULT_SCALE {Real}
  	Scaling factor of the result variable (a).
  	This keyword cannot be repeated and it expects precisely one real.

  RESULT_SPIN_INDEX
  	RESULT_SPIN_INDEX {Keyword}
  	Spin of the MO (y) to be modified.
  	This keyword cannot be repeated and it expects precisely one keyword.
  	Default value: ALPHA
  	List of valid keywords: ALPHA Majority spin BETA Minority spin
