If the Earth were the size of a basketball, a tightly held pillowcase would represent the thickness of the atmosphere. Enhancements have been made to most areas of the NIST REFPROP program, including the equations of state for many of the pure fluids and mixtures, the transport equations, the graphical interface, the Excel spreadsheet, the Fortran files (i.e., core property routines), the sample programs in Python, C++, MATLAB, VB, etc. If you can't find the necessary information in the Document Panel, take the Advanced Properties into use. AirPTWK, which calculates thermal conductivity given pressure, Specific Heat. @Air 3.2 is available as a Methane. The traditional CFCs R11, R12, R13, R113, R114, and R115.
