RO_VIRTIS_EAICD.PDF -  Adobe Acrobat version of EAICD
                    The EAICD (Experimenter to (Science) Archive
                    Interface Control Document) provides users of the
                    VIRTIS instrument with detailed description of the
                    product and a description of how it was generated,
                    including data sources and destinations. It is the
                    official interface between our instrument team and
                    the archiving authority.
