COSIMA data analysis using multivariate techniques

Autor: J. Silén, H. Cottin, M. Hilchenbach, J. Kissel, H. Lehto, S. Siljeström, K. Varmuza

Publikováno v: Geoscientific Instrumentation, Methods and Data Systems, Vol 4, Iss 1, Pp 45-56 (2015)

We describe how to use multivariate analysis of complex TOF-SIMS (time-of-flight secondary ion mass spectrometry) spectra by introducing the method of random projections. The technique allows us to do full clustering and classification of the measure

International audience; We related morphological (size/shape) and dynamical properties of the dust ejected from the 67P/Churyumov-Gerasimenko comet by combining data from two instruments onboard the ESA's Rosetta mission, i.e. the MIDAS atomic force

The D/H ratio is a clue to the origin and evolution of hydrogen-bearing chemical species in Solar system materials. D/H has been observed in the coma of many comets, but most such measurements have been for gaseous water. We present the first in situ
