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-R contains data for the time period between 1989-12-29 to 1994-12-31. The data are stored as an ASCII data file (*.TAB) and a detatched header file (*.LBL). Information regarding available software can be found in the /SOFTWARE directory of this disk. 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 time 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. This is followed by more detailed information about each data file. The Space Science Reviews (SSR) instrument paper can be found in DOCUMENTS directory. Reprinted by permission of Kluwer Academic Publishers. Novice users can ignore all directories and files except for those mentioned in this brief description. ============================================================================== Volume Set Information ============================================================================== This CD-R is the only disk of the GOMW_100x volume. This volume set contains Galileo cruise HIC, MAG, and trajectory data. The magnetometer data includes cruise EDR's, and processed data in inertial rotor and geophysical coordinates. This volume set will contain all interplanetary cruise data from launch through 1994-Dec-31. ============================================================================== 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 GO MWG CD-R (volume set GOMW_100X) created by this production date. The cumulative list of errata will also be found on the last disk of this volume series. ============================================================================== File Formats ============================================================================== All files on this disk are described by detached version 3.0 PDS labels. Most of the data files are time-series which are organized as ASCII files. The data file (.TAB) is an ascii table of data values. 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.

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 Mr. Joe Mafi of the PPI Node and verified for compliance with accepted PDS standards by Mr. Tyler Brown of the Central Node at JPL.
