Scientific paper

In this work we show the results obtained with the new VNIR transfer function of a previous study [1]. Moreover, the results regard also the Polar regions. Goal of this paper is mapping the 1 ?m from the OMEGA spectra in order to study the Martian mineralogy. In particular we search new spectral indexes around the 1 ?m absorption and the correlations between them. Due to the misalignment of the OMEGA VNIR and SWIR channels, spectral indexes related to the 1 ?m absorption have been usually computed considering the left or right edges of the absorption [2,3], without taking the band as a whole. In this work we report a method to co-register the VNIR and SWIR channels of the OMEGA instrument to compute the 1 ?m band integral, search new spectral indices and possible correlations between them.
