Dear all,

calculating the electron-phonon coupling factor (lambda) for Aluminum i obtained that it depends very strongly on the PP i use. 
Trying different PPs from the QE package i got lambda values from 0 to 4.5 when the known value is about 0.4. To calculate 
lambda i just performed example07 with different pseudopotentials. What did i do wrong?
