    • The uncertainties in the DMC energies are a combination of statistical and systematic uncertainties. The systematic uncertainties are thought to be small [D. Blume (private communication)].

    • Equation (62) assumes one can achive an exact fit Q= 1.0 with s=6 parameters, which is not quite possible with our fitting function. However, the fit with s=6 parameters is close enough to effectively give Q= 1.0

    • In practice, there are three-parameter potential fits with Q values slightly over 0.5. The four-parameter extrapolations, however, are clearly superior to the three-parameter extrapolations. Since the errors on the DMC energies are the result of a conservative appraisal [D. Blume (private communication)], we take the four-parameter potential fits to be optimal and attribute the Q values being slightly over 0.5 for the three-parameter fits to the cautious error analysis.
