  FERMI_EXP
  	FERMI_EXP {Real}
  	Exponent in the fermi-like constraint function.
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 2.63391000E+00

  SCALE
  	SCALE {Real}
  	Defines the upper and lower boundaries as (1+scale)*exp and (1-scale)*exp. Fermi-like constraint function
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 3.00000000E-01
