Local potential is PP. Cutoffs for other similar metals might be obtained by scaling the used cutoffs with the Wigner Seitz radius. Partial core is important and changes dimer length by . PP is optimized for a simulation of l-K with a cutoff of 60 eV. Very accurate calculations would require 80 eV.
