The definition of the mission phases is given in CATALOG/MISSION.CAT. The radio observations were carried out using the ROS spacecraft and Earth based receiving station in New Norcia, Australia (ESA), or the DSN stations (NASA). Each disc in the volume set contains data from one day of the mission phase. Data are organized in approximate chronological order, though receipt at Cologne was generally more important in determining placement than strict order of generation or applicability. If data are not or just incomplete available for archiving, the affected day will be skipped. The archiving of this day takes place some time later. For this reason a strict chronological order of data organization can not be adhered to. A table of contents is included with each volume, listing each file in the volume; a separate table of contents shows all files within the data set. The table below lists the individual volumes (CDs) created to date and (very briefly) their respective contents. RSI VOLUME ID VOLUME_ID Start Date Measurement ------------- ---------- ---------- ------------- RORSI_0001 RORSI_0001 2004-03-26 Commissioning RORSI_0002 RORSI_0002 2004-03-27 Commissioning ====================================================================== VOLUME SET INFORMATION ====================================================================== This disc is one of several which contain raw and partially processed data from the ROSETTA Commissioning 1. Each archive volume has the structure illustrated in the diagram below. Not all directories or file types will be present on every disc; for example, one volume may contain either IFMS or DSN Data Files. In cases where the directory contains no files, the directory itself has been omitted from the CD-WO volume. The primary data types for these volumes are if the data was retrieved from an ESA ground station IFMS closed-loop and open-loop data files. In case of data files received in ground station of the DSN system these are the DSN Radio-Science Receiver (RSR) data files, the Orbit Data File (ODF), and the Tracking and Navigation Data File (TNF). All these files are stored in the DATA folder in the root directory within appropriate subfolders. The primary data files are accompanied by a number of ancillary files in the CALIB directories and the ANCILLARY folders of the EXTRAS directories. CALIB and DOCUMENT files appear on every volume where they could be useful. Each of these files appears only once in the volume set; users should consult the tables of contents in the INDEX directory for file locations. The diagram below shows the organization of each volume, starting from the root of the compact disc. root | |- AAREADME.TXT |- ERRATA.TXT |- VOLDESC.CAT | |- BROWSE | | | |- BROWINFO.TXT Description of the BROWSE directory | which includes Quick Look Browse Plots | of the data. |- CALIB | | |- CALINFO.TXT Overview of directory | |- CLOSED_LOOP | |-IFMS IFMS closed-loop calibration files | |-DSN DSN closed-loop calibration files | |- OPEN_LOOP | |-IFMS IFMS open-loop calibration files | |-DSN DSN open-loop calibration files | |- UPLINK_FREQ_CORRECT | This folder will only be generated if | the uplink frequency in one of the .RAW | files was identified as wrong. | It tells the user which files were | affected and where to find the corrected | Level 2 data files. | |- CATALOG | | | |- CATINFO.TXT Streamlined PDS catalog files | |- MISSION.CAT for mission, host, instrument, | |- INSTHOST.CAT references, personnel, and | |- INST.CAT data set (files evolve as | |- REF.CAT mission progresses). | |- PERSON.CAT | |- DATASET.CAT | |- SOFT.CAT | |- TARGET.CAT | |- DATA | | | |- LEVEL1A | |- CLOSED_LOOP | |-IFMS IFMS closed-loop data files(Level 1a) | |-DSN DSN closed-loop data files (Level 1a) | |- OPEN_LOOP | |-IFMS IFMS open-loop data files (Level 1a) | |-DSN DSN open-loop data files (Level 1a) | |- LEVEL1b | |- CLOSED_LOOP | |-IFMS IFMS closed-loop data files(Level 1b) | |-DSN DSN closed-loop data files (Level 1b) | |- OPEN_LOOP | |-IFMS IFMS open-loop data files (Level 1b) | |-DSN DSN open-loop data files (Level 1b) | |- LEVEL02 | |- CLOSED_LOOP | |-IFMS IFMS closed-loop data files (Level 2) | |-DSN DSN closed-loop data files (Level 2) | |- OPEN_LOOP | |-IFMS IFMS open-loop data files (Level 2) | |-DSN DSN open-loop data files (Level 2) |- EXTRAS | | | |- ANCILLARY | |- SPICE SPICE Ancillary Data files | |- ESOC ESOC Ancillary Data files | |- UNIBW UniBW Ancillary Data files | |- RSI Level 2 Processing logfiles | |- SUE Modified Spice kernels | |- DSN Earth Orientiation Parameter files, | Light Time File and Orbit Propagation and | Timing Geometry File | |- INDEX | | | |- INDXINFO.TXT Overview of directory | |- INDEX.LBL Label to INDEX.TAB | |- INDEX.TAB List of data file contents, this volume | |- BROWSE_INDEX.LBL Label to BROWSE_INDEX.TAB | |- BROWSE_INDEX.TAB List of all files in BROWSE directory | | |-DOCUMENT | | | |- DOCINFO.TXT Overview of directory | |- RSI_DOC RSI documents | |- ESA_DOC ESA documents | |- DSN_DOC DSN documents documents 7 ====================================================================== ERRATA ====================================================================== A cumulative list of errors and changes is maintained in the file ERRATA.TXT at the root level of each volume. ERRATA.TXT in higher numbered volumes (or higher version numbers) will have errors for earlier volumes. ====================================================================== DISC FORMAT ====================================================================== The disc is organized according to the PDS standard for 'one data set, one volume.' This file (AAREADME.TXT), a PDS volume object definition (VOLDESC.CAT), and the listing of errors and changes (ERRATA.TXT) are included at the root level. The following directories of descriptive material are also at the root level: CALIB contains data files for data calibration, e.g. the IFMS Range calibration files and IFMS Meteo files containing Meteorological data from ground station. In case of DSN data the appropriate calibration files are tropospheric and ionospheric media calibration files Note: If the uplink frequency in one of the RAW files was identified as wrong the folder UPLINK_FREQ_CORRECT will contain files which identify which files were affected and where to find the corrected Level 2 data files. CATALOG contains descriptive files for cataloging the data on this disc. BROWSE contains Quick Look Browse Plots of the data. INDEX contains index information on each of the data files included in this disc; it also includes a cumulative index to all files in this volume set. DATA contains the scientific data of data level 1a, 1b and Level 2. The different data files are described with Detached labels. EXTRAS contains additional information which may help some users understand or manipulate data; The ANCILLARY subfolder contains ancillary data about spacecraft orbit, attitude clock conversions, planetary ephemerises and constants in two different formats: the NAIF SPICE software and the OASW software from ESOC. Additional data files from the Universitaet der Bundeswehr, Munich, are also stored in a appropriate subfolder, if available. Files in this directory are not considered part of the formal archive and have not been reviewed for completeness or accuracy. DOCUMENT contains the files that provide documentation and supplementary information to assist in understanding and using the data products on the volume. ====================================================================== FILE FORMAT ====================================================================== The file format of the data files on a volume depends on the data type, IFMS Or DSN data. The IFMS data files are all in ASCII format. The closed-loop and open loop DSN data files on the other hand are all binary. The Format description can be found in the DOCUMENT folders of the EXTRAS Directory. All documents in the DOCUMENT subdirectories are in the binary PDF Format, which can be read by nearly all standard text readers, e.g. Adobe Acrobat Reader. Most of the data files on the disc are accompanied by detached PDS labels, which describe their contents. Some data products have so called 'combined detached' labels, where one label covers two or more data files. Detached labels have the same file name as the data file except that the label name has the suffix 'LBL'. ====================================================================== SOFTWARE ====================================================================== Scientific Software for processing and analyzing of the RSI data files are not included in any RSI data volume. ====================================================================== ACKNOWLEDGMENTS ====================================================================== These data were collected under auspices of the Project M. Paetzold of the Rhenish Institute of Environmental Research at the University of Cologne as the Principal Investigator of the Radio-Science Experiment. He was also the Radio Science Team Leader. Members of the Team and its support elements involved in data acquisition and validation included Richard Simpson (Stanford University) and B. Haeusler (UniBW, Munich). ====================================================================== DISCLAIMER ====================================================================== Although considerable care has gone into making this volume set, errors are both possible and likely. Users of the data are advised to exercise the same caution as they would when dealing with any other unknown data set. Reports of errors or difficulties would be appreciated.
