Clouser and W. Gordy, 1964, Phys. Rev. {\bf 134}, A863. The dipole moment is taken from K. H. Hellwege, Ed., 1974, Landolt-B\"ornstein, Numerical Data and Functional Relationships in Science and Technology, Group II., Vol. 6, Molecular Constants, Springer-Verlag, Heidelberg. This calculation does not include the hyperfine splittings for the chlorine and potassium atoms.
