<b>Purpose of projwfc.x:</b>
projects wavefunctions onto orthogonalized atomic wavefunctions,
calculates Lowdin charges, spilling parameter, projected DOS
(separated into up and down components for lSDA)
alternatively, computes the local DOS(E), integrated in volumes
given in input
<b>Structure of the input data:</b>

<a name="idm89"><h4>Format of output files</h4></a>
<blockquote><pre>
Projections are written to standard output, and also to file
<a href="#filproj">filproj</a> if given as input.
The total DOS and the sum of projected DOS are written to file
"filpdos".pdos_tot.
* The format for the collinear, spin-unpolarized case and the
non-collinear, spin-orbit case is:
E DOS(E) PDOS(E)
...
* The format for the collinear, spin-polarized case is:
E DOSup(E) DOSdw(E) PDOSup(E) PDOSdw(E)
...
* The format for the non-collinear, non spin-orbit case is:
E DOS(E) PDOSup(E) PDOSdw(E)
...
In the collinear case and the non-collinear, non spin-orbit case
projected DOS are written to file "filpdos".pdos_atm#N(X)_wfc#M(l),
where N = atom number , X = atom symbol, M = wfc number, l=s,p,d,f
(one file per atomic wavefunction found in the pseudopotential file)
* The format for the collinear, spin-unpolarized case is:
E LDOS(E) PDOS_1(E) ... PDOS_2l+1(E)
...
where LDOS = \sum m=1,2l+1 PDOS_m(E)
and PDOS_m(E) = projected DOS on atomic wfc with component m
* The format for the collinear, spin-polarized case and the
non-collinear, non spin-orbit case is as above with
two components for both LDOS(E) and PDOS_m(E)
In the non-collinear, spin-orbit case (i.e. if there is at least one
fully relativistic pseudopotential) wavefunctions are projected
onto eigenstates of the total angular-momentum.
Projected DOS are written to file "filpdos".pdos_atm#N(X)_wfc#M(l_j),
where N = atom number , X = atom symbol, M = wfc number, l=s,p,d,f
and j is the value of the total angular momentum.
In this case the format is:
E LDOS(E) PDOS_1(E) ... PDOS_2j+1(E)
...
If <a href="#kresolveddos">kresolveddos</a>=.true., the k-point index is prepended
to the formats above, e.g. (collinear, spin-unpolarized case)
ik E DOS(E) PDOS(E)
All DOS(E) are in states/eV plotted vs E in eV
