Hello,
Do you know how I could go about verifying if this is the case? Especially
since the local term should become Coulombic in the limit of large distances
away, so there will be other components to this term as well (unless I'm
mistaken).
Also, in general, do you know how the reference states are selected for the
summation in the nonlocal term? Why might the d and f orbitals be selected in
this case?
Thanks for your help,

Dear Lance Kavalsky,
A wild guess: s was the local component of the pseudo potential? I
agree, the cut-off radius should have been listed though.
