[Pw_forum] eamp in Dipole Correction

[Giovanni Cantele]

eamp=0 if only the dipole correction is needed (dipfield=.true.), because in this case the amplitude of the correction is self consistently computed from the charge density. eamp is needed only if you need to add and external electric field.
