a) Measured I/J for all of the data listed in Table 2 without any photometric correction. The distinct geographical regions of the nucleus have very similar fluxes and spectral shape. There are no apparent absorption features in the spectra. The artifact at 1657 Å is due to a slight difference in wavelength registration and line width between the strong C i line in the solar spectrum measured by SEE and that reflected off of 67P and measured by Alice. b) Photometrically corrected I/J of 4 representative spectra of the regions (Hatmehit, Hapi, Seth, Ash) sampled and shown in panel a). Hatmehit, the depression on the small lobe of the comet, is an overall brighter region between 1500 and 1850 Å, whereas Ash may be slightly darker then the other regions between 1250 and 1500 Å.
