! Program: dos.x
! Purpose: calculates the Density of States (DOS)
! (separated into up and down components for lSDA)
!
! Input (namelist &inputpp ... &end): Default value
!
! prefix prefix of input file produced by pw.x 'pwscf'
! (wavefunctions are not needed)
! outdir directory containing the input file ./
! ngauss Type of gaussian broadening (optional) 0
! = 0 Simple Gaussian (default)
! = 1 Methfessel-Paxton of order 1
! = -1 Marzari-Vanderbilt "cold smearing"
! =-99 Fermi-Dirac function
! degauss gaussian broadening, Ry (not eV!) see below
! Emin, Emax min, max energy (eV) for DOS plot band extrema
! DeltaE energy grid step (eV) none
! fildos output file containing DOS(E) "prefix".dos
