| Popis: | This paper presents an enhanced approach to extract as much as possible information from raw measurements of a given solid-state detector. Here we focus on the benefits of a singular value decomposition approach applied to the special case of the CNES-JASON 2 mission. It allows us to extract more information from the sensor than a more traditional technique. Refined differential fluxes instead of only coarse integral and differential ones are now obtained and to get an improved resolution for both protons (40-500 MeV) and electrons (825 keV to 8 MeV). Finally, thanks to the combination of all the information embedded into the different response functions of the ICARE-NG instrument, we are now able to: 1) estimate the uncertainty of our measurements, and 2) automatically filter contamination from both proton and electron in restored fluxes channels. |
