Volume GOMW_0002 Galileo Orbiter MWG Browse Data Collection Earth 1 Flyby Planetary Plasma Interactions Node of the Planetary Data System ============================================================================== Introduction ============================================================================== This disk contains Earth 1 flyby browse data from the Galileo Orbiter Magnetosphere's Working Group (MWG) that has been submitted to the Planetary Data System (PDS) 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 CD-ROM contains data submitted to the PDS by the Energetic Particle Detector (EPD), the Magnetometer (MAG), the Plasma Analyzer (PLS), and the Plasma Wave Subsystem (PWS) experimeters. The Heavy Ion Counter (HIC) and the Dust Detector System (DDS) are both MWG instrument teams which have not submitted data for this particular volume. The DDS instrument has measured data throughout the cruise phase of the mission and that dataset will be archived on a cruise volume. The HIC instrument did not make measurements which they thought needed to be archived. The HIC team has made a statement of NULL results in lieu of a dataset for this flyby. 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 that includes December 7-9, 1990 are included on this volume. All data files are stored in the "DATA" branch of the directory tree. Each instrument is given a subdirectory and each dataset is located in a subdirectory beneath that. 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 directory. Again, the catalog directory is sub-divided by instrument. 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 CD-ROM is the second volume 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. ============================================================================== Disk Format ============================================================================== The disk is organized into a hierarchical directory structure which the PPI Node hopes will be both intuitive for the user as well as easy to use. The disk is formatted according to both ISO 9660 and POSIX (UNIX) standards in order to accommodate users on a wide variety of platforms. All of the label, table, and text files are ascii with CR/LF (VMS / IBM-PC) format. ============================================================================== Volume Contents and Structure ============================================================================== This section describes the volume structure and naming conventions. Below is a tree diagram of the CD-ROM, followed by a description of the directory function and key files in each directory. Note: There is a file called YMTRANS.TBL in every directory. This is characteristic of the CD-ROM production software. Also within each of the DATA sub-directories there is a file called ZZINPUT.PDS which is a necessary production file, but not for the user. Excuse any inconvenience that these files may cause. + DDS + EPD + CATALOG---+ HIC | + MAG | + PLS | + PWS | + TRAJECT | | + BROWSE | | | + EPD-+ | | | | | + HIRES | + HIC | | + DATA -----+ | | + BROWSE | | | CDROM------+ + MAG-+ | | | | | + HIRES | | | + PLS | | | + PWS | | | + TRAJECT | | | | + DDS + DOCUMENT -+ EPD | + HIC | + MAG | + PLS | + PWS | | + INDEX | + MANAGE | | + SOFTWARE CATALOG Contains mission, spacecraft, dataset, instrument, reference, and personnel templates organized into one file called CATALOG.CAT. key files: CATALOG.CAT - Contains all catalog templates.
