Continuum-subtracted VIRTIS-H spectra (blue) superimposed on the synthetic model that best fits the MB (2.590–2.760 μm) spectral region (orange). Top: H1 dataset. Bottom: H2 dataset. The standard deviation for each spectral channel is shown at the bottom of the plots (and vertically offset with respect to the measured radiances for better clarity). The MB spectral region is shown by a horizontal green line.
