[Pw_forum] Fourier interpolation

[sonu kumar]

*Dear Prof. **Eyvaz Isaev and QE users,*
*
*
*> Play around cutoff energy and the threshold parameter for phonons.

*
*where is the cutoff energy parameter related to phonon calculations?*
*
*
*i couldn't find it in the manual for ph.x. Only "tr2_ph"  theshold **parameter
is *
*there in addition to "eth_rps" and "eth_ns" **parameters for Raman
calculations.*
*
*
*i am sorry if am wrong.*
*Thank you very much.*
*
*
*With Kind Regards,*
