Data that may appear on this volume as version 1.1 was previously archived with the NSSDC and PDS as version 1.0. Changes include reformatting of the time column, standardization of flag values, and upgrading of labels and catalog templates to PDS version 3.2. Data found on this volume supersede all previous versions. Every effort has been made to insure 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 volume or its contents. Users are encouraged to verify the 'correctness' of the data prior to submitting any publications or other work based on these data. Brief Volume Description ---------------------- This data set is organized into 5 principal sub-directories: CATALOG PDS catalog templates describing the Voyager mission, spacecraft, instruments, data sets, key personnel and references DATA science data from the MAG (Fluxgate Magnetometer) instrument DOCUMENT documents describing instruments, data sets, or software contained on this volume INDEX index of all user files contained on this volume EXTRAS additional information More information on directory structure is contained in the section entitled 'Volume Contents and Structure.' Novice users, however, may ignore all files and directories except for the 'Important Files and Directories' listed below. Important Files and Directories ------------------------------- All data files are stored, either in ASCII (.TAB) or binary (.DAT) format files, in the /DATA branch of the directory tree. The content of each data file is described by a detached PDS label file (.LBL). A single format file (.FMT), which is pointed to by the label file (^STRUCTURE), describes the data file's internal structure or record format. The files DATASET.TXT and INFO.TXT provide additional information about data set and directory contents. An *INFO.TXT file (e.g. CATINFO.TXT, etc.), containing a description of the directory tree and sub-directory contents, is located in every directory immediately below the root. The INFO.TXT files provided on selected data sub-directories contain detailed descriptions of the directories on which they are located. Documents ========= The documents provided on this volume (in the /DOCUMENT sub-directory) include copyrighted materials previously published in Space Science Reviews, Vol. 21, No. 2, pp. 77-101, November 1977, and Space Science Reviews, Vol. 21, No. 3, pp. 235-376, December 1977. These materials appear on this volume with the permission of Kluwer Academic Publications (Kluwer). Kluwer retains Copyright over these articles. Please see the Copyright statement appearing at the beginning of each of the Space Science Reviews articles. File Formats ============ All of the label, table, and text files are ASCII format. All files in this volume are described by detached or combined detached PDS labels. PDS labels have a file extension of '.LBL' and generally have the same name as the file which it describes. All PDS label files in this volume are completely PDS Standards Version 3.8 compliant. Data files are either stored in ASCII (.TAB), or binary (.DAT) format. ASCII file records are generally fixed length with space delimited fields or columns. Refer to the label (.LBL) and format (.FMT) files for information about the format and structure of a specific data file. This volume contains copies of documents associated with the data provided. These documents are reproduced in both plain ASCII text (.ASC) and PDF(.PDF) versions. Errata ====== For a description of any errors known at the time of the production of this volume, please refer to the file ERRATA.TXT found in the root directory. Volume Contents and Structure ============================= The tree diagram below provides a listing and brief description of the contents and key files of the root directory and instrument sub-directories of the /DATA directory. Note that some files may be omitted from this description. Each file in this volume (with the exception of *.CAT files) is associated with a PDS label file (.LBL) which describes its content and characteristics. For more information, please refer to the *INFO.TXT files located on each of the sub-directories of the root directory, or the INFO.TXT files located on the individual data sub-directories. Square brackets ([]) denote directories.

The actual encounter data (1986-01-24T07:00:00 -> 1986-01-25T04:00:00) are provided in the Uranus Longitude coordinate system. The magnetometer data in the solar wind are given in Heliographic coordinates and the data have been averaged from the 9.6 second resampled data to a 48.0 second sampled rate. Contacts ======== The person most directly responsible for the construction and release of this volume is Mr. Steven Joy. He was the PPI Node Data Administrator at the time this volume was created and understands as much about the structure and data organization as anyone. The construction of the PDS labels and templates was done by Mr. Joe Mafi. Other PPI personnel who may be aware of about issues related to this volume include Dr. Raymond Walker, the PDS/PPI node manager.
