Very simple PP, accurate norm conserving description for d was included, but is not really necessary for K. 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 $2 \%$. PP is optimized for a simulation of l-K with a cutoff of 60 eV. Very accurate calculations would require 80 eV.
