  USE_FINER_GRID
  	USE_FINER_GRID
  	Uses a finer grid only to calculate the xc
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  XC_DERIV
  	XC_DERIV NN10_SMOOTH
  	The method used to compute the derivatives
  	This optional keyword cannot be repeated and it expects precisely one keyword.
  	Default value: PW
  	List of valid keywords: COLLOCATE NN10_SMOOTH NN4_SMOOTH NN50_SMOOTH NN6_SMOOTH PW SPLINE2 SPLINE2_SMOOTH SPLINE3 SPLINE3_SMOOTH

  XC_SMOOTH_RHO
  	XC_SMOOTH_RHO NN10
  	The density smoothing used for the xc calculation
  	This optional keyword cannot be repeated and it expects precisely one keyword.
  	Default value: NONE
  	List of valid keywords: NN10 NN4 NN50 NN6 NONE SPLINE2 SPLINE3
