Values given at 1 K intervals (finer intervals below 10 K) for helium (both mass 3 and 4 isotopes), neon (both mass 20 and 22 isotopes), and argon (mass 40 isotope).  Upper temperature limit is 2000 K in all cases. Lower temperature limit is 0.5 K for helium, 4 K for neon, 50 K for argon.\nThese files are Supplemental information to: G. Garberoglio and A.H.
