MATISSE v0 5 user manual 24th July 2013 MATISSE Multi purpose Advanced Tool for Instruments for the Solar System Exploration is a web based tool to access and visualize data from planetary exploration instruments The version here documented is intended to be a Demo as it has little scientific capabilities In this document the main functionalities of the software will be illustrated New in this version Version 0 5 can be considered an almost stable release as it also includes the visualization of GIADA simulations and most notably the implementation for the multi instrument use thus allowing data fusion Accessing the tool In order to be able to access the MATISSE web page it is fundamental to register on https tools asdc asi it cas login and then send a mail to angelo zinzi asdc asi it with the username chosen this is needed to be added to the MATISSE group After the registration procedure has been completed the user can access the web page https tools asdc asi it matisse jsp The selection form In this version it is possible to select target mission instrument wavelength latitude longitude box color table number of colors and observation one for every step The targets present at the time are the asteroid 21 Lutetia and the comet 67P Churyumov Gerasimenko The only mission selectable is Rosetta while the instruments are OSIRIS NAC OSIRIS WAC VIRTIS M VIS VIRTIS M IR and the different GLADA measur
