[Pw_forum] core radius of pseudopotential for which matches real wave function

[mike at.]

hi,

how can i tell the core radius ( cuttoff radius) ,  r_c , at which a pseudo
potential is valid? ir for something like  B.pz-vbc.UPF, how can i find out
from which values the pseudo matches the *real* wavefunction?
