Data for Figure 7 shows the time since onset of degassing, and the composition of the atmosphere at the point where either H2 or CO2 has a greater abundance than H2O according to the file name. In The H2 file, if the age shows than 12 Gyr H2 may not yet be the most abundant species, but this is the closest datapoint to the H2-H2O transition and is helpful for plotting the contours of Fig 7.
