[Pw_forum] epsilon_0

What QE calculates is the dielectric tensor at clamped ions
(often referred to as \epsilon_\infty). The ionic contribution
must be calculated and added to this in order to obtain the
static dielectric tensor (\epsilon_0). Does the most recent
version of QE print "\epsilon_0" somewhere in the output file ?

Thanking you and with my best regards,
