XCKernel 
Section  Hamiltonian::XC  
Type  integer 
 
Defines the exchange-correlation kernel. Only LDA kernels are available currently.
The options are the same as XCFunctional .
Note: the kernel is only needed for Casida, Sternheimer, or optimal-control calculations.
Defaults:
 1D: lda_x_1d + lda_c_1d_csc 
 2D: lda_x_2d + lda_c_2d_amgb 
 3D: lda_x + lda_c_pz_mod 
 
Options :
   xc_functional : 
The same functional defined by XCFunctional .
