[Pw_forum] vdW

[Alexandra Davila]

Hi QE users,

in order to calculate energies with the vdw functional, I have used 
input_dft = 'vdW-DF'.

At the beginning of the output file, it is written: 
Exchange-correlation      = VDW-DF ( 1  4  4  0 1 0)
what do the ( 1  4  4  0 1 0) numbers mean?

Thanks !
