[QE-users] How to plot phonon band structure with LO-TO splitting

[Dr. K. C. Bhamu]

Dear Lorenzo,

My motive  is to plot phonon band structure with and without LO-TO
splitting in a single plot and I would run (may be  wrong but giving it a
try)  two separate gamma calculation one with epsil=.false. and other with .
true. for this.

If you have any previous experience then you can save my computational time.

regards
Bhamu
