The Wigner Seitz Radius is approximately 2.8 a.u.,
cutoffs for other transition metals might be obtained by scaling
the used cutoffs with the Wigner Seitz Radius.
s- and p-PP are normconserving, s-PP is local.
d-PP is ultrasoft with 2 reference energies.
Partial core corrections are selected, and are important for
the transition elements at the beginning of the row.
The cutoff for the s-PP was made as small as possible
without creating a node in the s-wavefunction (it is
also possible to set ITYPE to 15
and set R 
for the s part, but differences are negligible).
A node in the s-PP must be avoided, because the s PP
is the the local potential (ICORE=0).
The pseudopotential is real space optimized for a
cutoff of 160 eV for a simulation of liquid V. Very accurate
calculations would require approximately 200 eV.
