[Pw_forum] Are the wlog, Tc got from lambda.x reasonable?

[Chen Si]

    Hi, everybody.

    In the version 4.3.2 of Quantum espresso,  the lambda.x reads the files
"filelph" produced by phonon calculations to get the electron-phonon
coefficient (lambda) , wlog and superconducting temperature (Tc).  So only
a course q grid used in the phonon calculations is summed over in the
lambda.x.  I found in some systems the lambda obtained from lambda.x is
quite different from the value got form matdyn.x, which is based on a dense
q grid.  In this respect, are the wlog, Tc got from lambda.x reasonable?
If not, how can I obtain reasonable wlog?

   Thanks.

   Any help will be appreciated.
