Local potential is s-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.
