VIRTIS-H average spectra of H2O and CO2 bands observed from 10 to 17 October 2014 (rh ~ 3.2 AU), in spectral orders 4 and 0, respectively. The continuum has been subtracted. Superimposed we show a model spectrum of the ro-vibrational structure of H2O (ν1 and ν3) and CO2ν3 bands. Derived CO2 and H2O column densities are ~1 × 1018 and 2 × 1019 m-2, respectively.
