Zusammenfassung
During CassiniJupiter flyby occurred in December 2000, Visual-Infrared
mapping spectrometer (VIMS) instrument took several image cubes of
Jupiter at different phase angles and distances. We have analysed
the spectral images acquired by the VIMS visual channel by means
of a principal component analysis technique (PCA). The original data
set consists of 96 spectral images in the 0.35-1.05 mum wavelength
range. The product of the analysis are new PC bands, which contain
all the spectral variance of the original data. These new components
have been used to produce a map of Jupiter made of seven coherent
spectral classes. The map confirms previously published work done
on the Great Red Spot by using NIMS data. Some other new findings,
presently under investigation, are presented. (C) 2004 Published
