Extended Data Fig. 2: Model atmosphere parameters and results for the corresponding oxygen intensities.

From: A sublimated water atmosphere on Ganymede detected from Hubble Space Telescope observations

Extended Data Fig. 2

The temperature of the electrons is assumed to be Te = 100 eV. Maps of the model atmospheres are shown in Extended Data Figure 3. Note that the O2 atmosphere produces the vast majority of the OI1356 Å emissions. For the OI1304 Å emissions, in contrast, O2, O and H2O all have relevant contributions to the signal.
