[QE-users] Which matrix the 'fildvscf' tag will calcualte?

[半城烟沙]

Dear,
I want to now which matrix the 'fildvscf' tag will calcualte. The <nk|∂ Vscf / ∂τ |n'k+q> or  <nk|∂ Vscf / ∂τ |n'k+q> * e , where τ is atom displacement and e is the eigenvector of phonon. Anyone can help me?
Best regards,
Jiang
