[Pw_forum] dosup and pdosup in pdos_tot file

[B. Koa]

   Dear PWScf Users and Gabriele

   As I have read in the tutorial_magn.pdf which prepared by Paolo Giannozzi
they are too close to each other but not exactly the same as each other and
I don't understand the meaning of dosup and pdosup in the pdos_tot file
well; but generally I know the definition of DOS and PDOS. Also some values
of dosup and pdosup in the pdos_tot file have negative sign ! (at higher
energies ) but there are not such negative sign of dosup in the *.dos file.
What do the negative values mean?

  Truly Yours
  Koa
