Hi I don't have a background knowledge in XAS and how to interpret its data from WIEN2k. Could anyone please suggest me a book/paper in this context?

Using standard inputs I have been able to obtain ground state K-edge and L-edge XAS. At the next step I wanted to incorporate core-holes in my calculation. So for that I created supercell (2x2x1). The first atom (Fe) in my structure has core electrons as specified in case.inc: ----------------------------------------------------------------------------------------------------------------------------------------- 5 0.00 1 NUMBER OF ORBITALS (EXCLUDING SPIN), SHIFT, IPRINT 1,-1,2 ( N,KAPPA,OCCUP) 2,-1,2 ( N,KAPPA,OCCUP) 2, 1,2 ( N,KAPPA,OCCUP) 2,-2,4 ( N,KAPPA,OCCUP) 3,-1,2 ( N,KAPPA,OCCUP) ----------------------------------------------------------------------------------------------------------------------------------------- If I want to obtain K-edge of 1st atom, I just need to remove 1 electron from 1s level of the 1st atom. But my question is how can I modify case.inc for obtaining L23 edge of the 1st atom? I mean, from which line should I remove the electron (the 4th or the 5th line of case.inc) from 2p1/2 or 2p3/2? Thank you very much in advance for your kind help.
