[Pw_forum] DOS per eV per volume

[Guido Fratesi]

Dear Pari,
from Doc/INPUT_PROJWFC:
"All DOS(E) are in states/eV plotted vs E in eV"
i.e., states/eV/cell; if you want them in states/eV/volume you should 
divide by volume/cell.
To be sure, you can try once integrating numerically (histograms would 
be enough) the DOS up to the Fermi level to see you get the number of 
electrons (or the electron density) you expect for your system.
