[Pw_forum] Definition of PsP in LDA+U

[Sergey Lisenkov]

Dear Pwscf users and authors,

 I look at input file of example 25 of espresso distribution and see:

.....
ATOMIC_SPECIES
 O1   1.  O.LDA.US.RRKJ3.UPF
 Fe1  1.  Fe.pz-nd-rrkjus.UPF
 Fe2  1.  Fe.pz-nd-rrkjus.UPF
........

Why all masses of PsP are equal to 1? Does it affect to calculations?

 Thanks, 
   Sergey
