[Pw_forum] phonon dos normalization

[W. YU]

Dear PW users,

After several testing, I found that the phonon density
of state from the PWscf calculations are normalized to
six times the number of atoms in a unit cell. That is
twice of the degrees of freedom. I wonder why don't we
just normalize it to the degrees of freedom or just to
one?

I would appreciate it very much if someone could give
me an explanation.

W. YU
