Fig. 2


The 6300.304 Å, 6363.776 Å and 5577.339 Å oxygen lines (telluric (⊕) and cometary) in a 3600 s spectrum of comet 8P/Tuttle obtained in March 2008. Thanks to the high resolution of the UVES spectrograph, the cometary and telluric lines are well separated when the Doppler shift is larger than 15 km s-1. These spectra are representative of the quality of the sample.
