Dear all users,

I set london=.true. in the PW input file and the output is:

Program PWSCF v.5.0.2 (svn rev. 9656) starts on 19May2014 at  9:47:57 
     This program is part of the open-source Quantum ESPRESSO suite
     for quantum simulation of materials; please cite
         "P. Giannozzietal., J. Phys.:Condens. Matter 21 395502 (2009);
          URL http://www.quantum-espresso.org", 
     in publications or presentations arising from this work. More details at
     http://www.quantum-espresso.org/quote.php

     Parallel version (MPI), running on     8 processors
     R & G space division:  proc/nbgrp/npool/nimage =       8

     Current dimensions of program PWSCF are:
     Max number of different atomic species (ntypx) = 10
     Max number of k-points (npk) =  40000
     Max angular momentum in pseudopotentials (lmaxx) =  3

==================================================
I do not know why the value of C_6 parameter of Au is just a * symbol !!!!???

Any help will be appreciated,
