END_OBJECT = TEXT END Volume GOMW_0004 Galileo Orbiter MWG Browse Data Collection Gaspra Flyby Planetary Plasma Interactions Node of the Planetary Data System ============================================================================== Introduction ============================================================================== This volume contains Galileo Orbiter Magnetosphere's Working Group (MWG) data that has been submitted to the Planetary Data System (PDS) for the Gaspra flyby. Every effort has been made to assure that the data are of the best quality available. However, the PDS and the Planetary Plasma Interactions (PPI) Node in particular, assume no liability for this disk or its contents. All users are encouraged to verify the 'correctness' of the data prior to submitting any publications or other work based on these data. ============================================================================== Brief Disk Description ============================================================================== This volume contains data submitted to the PDS by the Magnetometer (MAG), the Plasma Analyzer (PLS), and the Plasma Wave Subsystem (PWS) experimeters. Neither the Heavy Ion Counter (HIC), nor Dust Detector System (DDS) instrument teams have submitted data for archival on this volume. The DDS instrument has measured data throughout the cruise phase of the mission and that dataset will be archived on the Jupiter volumes. The HIC team has made a statement of NULL results in lieu of a dataset for all of the encounters included of these volumes except the launch sequence data. This disk primarily contains 'browse' or quicklook datasets. If high resolution datasets were provided by the instrument team, then the subset of high resolution data about the primary encounter period is included on this volume. All data files are stored in the 'DATA' branch of the virtual volume directory trees. Each instrument is given a subdirectory and each dataset is located in a subdirectory beneath that. Most data are stored in ASCII tables which are described by a detached PDS label (.LBL) and format file (.FMT). Metadata are stored as text files with the data. The particular form of meta- data which forms the PDS catalog can be found in the CATALOG directories of the virtual volumes. Any documents which have been provided for inclusion of this volume can be found in the DOCUMENTS directory. In particular, all of the Space Science Reviews (SSR) instrument papers can be found in subdirectories of the DOCUMENTS directory. Reprinted by permission of Kluwer Academic Publishers. Users of this disk should read the INFO.TXT files located in each data directory which describe the data in that directory, as well as the other files in that directory. Although the INFO.TXT file is quite large it contains the most relevant information first. It begins by describing the type of data in the directory, the orbits covered, and the names of the most useful user files. Next the file naming conventions are described and the structure of the data files is given. More detailed information about each data file is then given. Novice users can ignore all directories and files except for those mentioned in this brief description. ============================================================================== Volume Set Information ============================================================================== This volume is the first disk of the GOMW_xxxx series. This volume set contains MWG browse data from the Earth, Venus, and asteroid flybys. ============================================================================== Errata ============================================================================== There is a file called ERRATA.TXT found at the root level of this volume which contains a list of changes and errors if there are any at the time this CD was published. This is a list of cumulative changes made to any GOMW_xxxx (volume set GOMW) created by this production date. Any changes or errors that were found to any GOMW volume after the production of this volume can be found at http://www.igpp.ucla.edu/public/pds/ERRATA/GOMW_000X/ERRATA.TXT. ============================================================================== Software ============================================================================== The Planetary Plasma Interactions (PPI) Node of NASA's Planetary Data System (PDS) provides software to facilitate the location of the data of interest on CD-ROM data products, as well as software to convert data between architecture specific data formats. In addition, the PPI Node provides software which has been made available by individual projects which may be useful when working with PPI data. Non-PDS software is provided 'as is' and is distributed by the PPI Node as a service to the community. To obtain the most recent release of any PPI distributed software use anonymous FTP to connect the PPI FTP server located at 'pdsppi.igpp.ucla.edu'. (Complete instructions on using FTP can be found in the SOFTWARE directory in the file 'FTP.TXT'). ============================================================================== File Formats ============================================================================== All files on this disk are described by detached version 3.0 PDS labels. Version 3.0 of the PDS label does not support detached TEXT file labels, however, TEXT file labels are detached on this disk. PDS labels are identified by a .LBL file name extension. There is one label file for each text and data file contained on this disk and the file name prefix is the same as the file the label describes. If the dataset is stored as multiple files (as most of them are), there will be a single format file which describes the physical structure of the data. This format file is then pointed to by all of the labels. Both the label files and the format files (*.FMT) are all located in the same directories as the data they describe. ============================================================================== Volume Contents and Structure ============================================================================== CATALOG Contains mission, spacecraft, dataset, instrument, reference, and personnel templates organized into one file called CATALOG.CAT. DATA Contains all data in a branching tree structure of sub-directories. DOCUMENT Contains the Space Science Reviews (SSR) instrument papers which describe the Galileo fields and particles instruments. Each document is stored in its own directory. All of the documents have been scanned electronically and stored as plain ASCII text (with all graphics missing). In addition, all figures complex equations have been scanned in and stored as bit map image files in TIFF format. key files: DOCINFO.TXT - Describes the contents of the DOCUMENT directory. INDEX Contains a file (INDEX.TAB) which gives the name and location of all files on this volume. These index files have been provided for users who do not wish to make use of the DITDOS software. key files: INDEX.TAB - Contains an index of this volume INDEX.LBL - Describes the columns and format of INDEX.TAB. INDXINFO.TXT - Describes the contents of this directory. ============================================================================== Point of Contact ============================================================================== If the user has problems reading this disk or can not make use of it on one or more of the platforms which should be supported, please contact the PPI pds_operator.

He was the PPI Node Data Administrator at the time this disk was created and he understands as much about the disk structure and data organization as anyone. The construction of the PDS labels and templates was done by Ms. Eva Fried of the PPI Node and Ms. Sue Hess and Ms. Ruth Monarrez of the Central Node at JPL. Mr. Mike Martin of JPL has helped to insure this disk conforms to accepted PDS standards.
