O2 provides ideal gas thermodynamic properties for oxygen gas valid over the temperature range from 200 K to 3500 K based on property information from McBride et al. (2002). The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25°C. The reference state for specific entropy is based on the Third Law of Thermodynamics. The reference values are from:
Bonnie J. McBride, Michael J. Zehe, and Sanford Gordon
"NASA Glenn Coefficients for CalculatingThermodynamic Properties of Individual Species"

Transport property correlations are implemented for temperatures between 200 K and 3000 K using correlations provided by N.B. Vargaftik, Y.K. Vinogradov and V.S. Yargin, Handbook of Physical Properties of Liquids and Gases, 3rd ed, 1996, ISBN 1-56700-063-0. (There is a typographical error in equation (1) on page 909. The 3rd coefficient should be a negative value, i.e., -408.723
Note that O2 provides thermodynamic properties assuming ideal gas behavior. Use OXYGEN to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
