[Wien] DOS unit

[Salman Zarrini]

Dear all,

As far as I know the density of states (DOS) is generally defined as the
number of electron states per unit volume per unit energy which simply
means that the unit of DOS should be states/(cm^3 eV) or states/(\AA^3
eV) in agreement with unit 1/(m^3 J) given for DOS in IUPAC Green Book -
Solid states section. Nevertheless, the unit assigned for DOS in most of
the literatures as well as here in Wien2k is just states/eV (or
state/energy) so that the 1/volume is somehow missing!
So, I would be so thankful if one could elaborate where I am wrong and what
the proper unit for DOS is?
One more issue (at least for me) is the concepts such as `` Projected
DOS'', `` Partial DOS'' and `` Local DOS'' which are heavily intermixed in
literatures, so, would you please let me know what the differences among
Projected, Partial and Local DOS are? And where each should be used?
