    "description": "During work on the new reference equation of state for carbon dioxide [A.H. Harvey, S.A. Tashkun, R. Hellmann, and E.W. Lemmon, J. Phys. Chem. Ref. Data, in preparation], we obtained unpublished data from several sources.  These represent numerical values for data only presented graphically in a publication, or in some cases data not present in the publication at all. With the permission of the authors, we document and deposit these data here so they will be available for future workers.  These include data for the melting curve at high pressures, the isochoric heat capacity (including near the critical point and in the two-phase region), the sound speed and density at high pressures, and the vapor pressure of the liquid.  It also includes values of the second, third, and fourth virial coefficients calculated by R. Hellmann from state-of-the-art pair and three-body potentials.For ease of electronic processing, the data elements are formatted as comma-separated values (.csv).More details about the file contents are in the README.txt file and in the headings of individual files.",
