¹Number of measurements.
²The original errors are given for the literature data, the standard deviations for this work.
³The uncertainties are mainly determined by those in thermodynamic functions.
⁴The uncertainty of the recommended values was calculated by Student’s method (monomer) and accepted as the third law ones (others).
