  ! emax (THz)    : alpha2F is plotted from 0 to "emax" in "nex" steps
  ! degaussq (THz): gaussian smearing for sum over q
  !                 NB: not the same used in phonon !
  ! ngaussq       : 0 for simple gaussian, 1 for Methfessel-Paxton etc.
  ! nks           : number of q-points used in the sum
  ! q, wk         : q-points and weights
  ! filelph       : output files from phonon, one for each q-point
  !                 May contain "nsig" calculations done with different
  !                 broadenings for the sum over k - all of them are used
  !
  ! OUTPUT in xmgr-readable format: files 'lambda.dat' and 'alpha2F.dat'
