Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.


11) Calculated from correlation between the polarizabilities and solubilities of stable gases. The temperature dependence is an estimate of the upper limit.
13) In the abstract, Schwartz (1984) gives a range of 9.9 mol/(m3 Pa) < Hcp < 3.0×101 mol/(m3 Pa). The mean value of this range (2.0×101 mol/(m3 Pa)) has been used by Lelieveld and Crutzen (1991), Pandis and Seinfeld (1989), and Jacob (1986).
14) The value of H was taken from Schwartz (1984).
