Example Alice spectral image acquired at 11:22:51 UT on 2015 July 1, when 67P/C-G was 1.35 au from the Sun, Rosetta was 160 km from the comet center, and the solar phase angle was 89.°6. The nucleus (orange shaded region) and extracted coma rows (blue shaded region) are labeled, along with the positions of several atomic emission lines and the instrumental feature (red shaded region) affecting wavelengths ≲1000 Å (Noonan et al. 2016).
