The data has been treated to remove some cross talk between different sectors (look directions) and mass channels. The moments have been calculated Using integration over available energy range and look directions. The solar wind ions have been semi-manually selected when instrument mass resolution allowed this. The value zero in the solar wind ions (H+,H2+,He+) Typically means that no solar wind ions were observed, but in the preliminary data set it may also mean that mass resolution was too poor to allow mass separation using mass data. Often it is in such cases possible to determine mass from the energy spectra. This has not been done for this data set. 67P/CHURYUMOV-GERASIMENKO 1 (1969 R1) RPC-ICA Data Archive ========================================================== a) DATA ======= CODMAC Level/Type Data Type Data Content 5 / Derived Data table Moment data derived from ICA measurements The data can be found in directories of this type: DATA/MOMENT/2004/SEP/D23 DATA/MOMENT/year/month/Dday/*.TAB (ICA data files) *.LBL (PDS LABEL files for the data files) All data files are in ASCII text format. b) Supporting files =================== Supporting files for the Archive user include PDS descriptions, documents, and searchable indices. These have been organized into five directories one level below the root: CATALOG, DOCUMENT, GEOMETRY & INDEX. Structure of the Volume ======================= AAREADME.TXT (PDS required introduction to the data set) VOLDESC.CAT (PDS required volume description of the data only) CATALOG/CATINFO.TXT (Description of the contents of the CATALOG directory) *.CAT (Mission, spacecraft, instrument, data, references) DOCUMENT/DOCINFO.TXT (Description of the contents of the DOCUMENT directory) *.LBL (PDS LABEL files for documents) *.ASC (ASCII text documents) *.DOC (WORD documents) *.HTM (HTML documents) *.PDF (PDF documents) *.PNG (PNG pictures) /SOFTWARE/SOFTINFO.TXT (Description of the contents of the SOFTWARE directory) *.LBL (PDS LABEL files for software files) *.M (Matlab source code files) GEOMETRY/GEOMINFO.TXT (Description of the contents of the GEOMETRY directory) *.LBL (PDS LABEL files for geometry files) *.PDF (PDF geometry files) *.JPG (JPEG geometry pictures) INDEX/INDXINFO.TXT (Description of the contents of the INDEX directory) INDEX.LBL (PDS LABEL file for INDEX.TAB) INDEX.TAB (Index of the DATA directory in tabular format) The ROSETTA project decided that the data would be archived in the PDS format. Consequently, the layout of this volume and the labels for each file conform the PDS guidelines.
