I have read the siesta-2.0.2 manual, and I wonder the ProjectedDensityOfStates.
The manual said that The block must be a single line with the energies of the
range for PDOS projection, (relative to the program's zero, i.e. the same as
the eigenvalues printed by the program), the peak width (an energy) for
broadening the eigen-
values, the number of points in the energy window, and the energy units. An
-20.00 10.00 0.200 500 eV
I wonder "relative to the program's zero," what it means? it means that the
density of states is relative to fermi energy and "-20.00" is relative to the
fermi energy or "-20.00" is an absolute value and I have to minus the fermi
energy by myself when I plot the density of states ?
