INTRODUCTION
==============================================================================
This electronic media contains archival raw, partially processed, and
ancillary/supporting radio science data acquired during the
ROSETTA PRELANDING.
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.

VOLUME SET INFORMATION
======================================================================
This volume is one of several which contain raw and partially processed
data from the ROS phase ROSETTA PRELANDING.
Each archive volume has the structure illustrated in the diagram below.
Not all directories or file types will be present on every volume; 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 volume.
The primary data types for these volumes are IFMS closed-loop and
open-loop data files if the data was retrieved from an ESA ground
station. These files are the Level 1a/1b files (RAW), which contain
the data as recorded at the ground station and the Level 2 files
(TAB), which contain calibrated frequency data. In case of data files
received with DSN ground stations, 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. Additional documents providing information on the
spacecraft, ground stations, used software and data processing
steps can be found in the DOCUMENT directory. 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.

======================================================================
ERRATA
======================================================================
A cumulative list of errors and changes is maintained in the file
ERRATA.TXT at the root level of each volume. The ERRATA.TXT file of
the latest volume will list errors occured in earlier volumes.
======================================================================
DATASET FORMAT
======================================================================
The dataset 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
Meteo 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.
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 Level 1a closed-loop and open loop DSN data files on the other
hand are binary, while the Level 2 files are in ASCII format. 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 in the dataset 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 Rosetta Project.

University of Cologne as the Principal Investigator of the
Radio-Science Experiment RSI was the team leader. Members of the
team, including B. Haeusler (UniBW, Munich) were involved in data
acquisition and validation.
======================================================================
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.
Please contact one of the persons listed below.

COGNIZANT PERSONNEL
======================================================================
The person most directly responsible for construction and release of
this volume set is Martin Paetzold (PI). Although many people
contributed to the volume set, any faults in the product
are his alone.
