Dear Wien users,
I entountered a problem in matching the partial DOS of each atom to the
total DOS of the material. The material contains only Mg (atom1,
multiplicity=2) and Si (atom2, multiplicity=1). I calculated the total,
Mg-s,p and Si-s,p density of states.
However, problem occured when I compared the total DOS with the sum of
weighted atomic partial DOS.
case.int
ATOM 1 tot,0,1,2,D-eg,D-t2g,3
ATOM 2 tot,0,1,2,D-eg,D-t2g,3

*********************
As you can see, the sum (column3+column4)*2+(column5+column6) is not equal
to column2. Column2 is the total DOS (inside sphere+instital). Does the
partial DOS for s or p also include the corresponding interstital states?
If it does not, where can I get those interstial states and add them to
match the total. If it does, what are the possible mistakes which can
cause the mismatch? I it contains the interstitial states since the
userguide says just summing ove them with consideration of multiplicity.
Many thanks
