END_OBJECT = TEXT END Voyager 1 at Jupiter Correlative Fields and Particles (VG_1501) CD-R of the Planetary Data System 1979-02-28 to 1979-03-22 Introduction ============ This CD contains data recorded during the Voyager 1 Jupiter Encounter and submitted to the Planetary Data System (PDS) by Voyager CRS, LECP, MAG, PLS, PRA, and PWS investigators. While the full Jupiter Encounter Phase has been defined as 1979-01-06 to 1979-04-13, this archive is limited primarily to the period from 1979-02-28 to 1979-03-22 (inclusive). These dates define the Voyager 1 Jupiter 'near encounter' interval as well as corresponding to Voyager 1's first and last crossings of the Jovian bowshock. This period spans all Jupiter-related data for most of the instruments for which data is archived. Since, however, the PRA instrument can record planetary phenomena at much larger ranges than the other fields and particles instruments, PRA coverage includes the full Jupiter Encounter Phase 1979-01-06 to 1979-04-13. Data sets appearing on this volume as version 1.1 were 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 sets found on this CD 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 disk 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 Disk Description ---------------------- This CD is organized into 7 principal sub-directories: CATALOG PDS catalog templates describing the Voyager mission, spacecraft, instruments, data sets, key personnel and references DATA science data from the following instruments: CRS (Cosmic Ray Subsystem), LECP (Low Energy Charged Particle), MAG (Fluxgate Magnetometer), PLS (Plasma Science Experiment), PRA (Planetary Radio Astronomy Receiver), and PWS (Plasma Wave Receiver) DOCUMENT documents describing instruments, data sets, or software contained on this volume GEOMETRY copies of the SPK, PCK, and LSK SPICE kernels INDEX index of all user files contained on this volume MANAGE inventory files; used by the PDS/PPI node for making this volume available on its website SOFTWARE executables and source code, plus instructions for obtaining any other software that may be available, for use with the data 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. Volume Series Information ========================= This CD is the first volume of the 'VOYAGER AT JUPITER - FIELDS AND PARTICLES LOW RATE SCIENCE' (VG_15xx) volume set. Volumes in this set include: Medium Volume ID Type Volume Name --------- ------ ----------------------------------------------------- VG_1501 CD-WO Voyager 1 at Jupiter Correlative Fields and Particles VG_1502 DVD-R Voyager 2 at Jupiter Correlative Fields and Particles Also available from the PDS is Voyager PWS Waveform Wideband Data (10 volumes from VG1, and 4 volumes from VG2).

Documents ========= The documents provided on this CD (in the /DOCUMENT sub-directories) 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 CD 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 with CR/LF (VAX/IBM-PC) format. All files on this disk 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 on this CD are completely PDS Standards Version 3.2 compliant. Data files are either stored in ASCII (.TAB), or binary (IEEE or VAX) format (.DAT). 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 CD contains copies of documents associated with the data provided. These documents are reproduced in both plain ASCII text (.ASC) and HTML (.HTM) versions. Figures, tables and equations from the original documents have been scanned and are provided in GIF89A format. Errata ====== For a description of any errors known at the time of the production of this CD, please refer to the file ERRATA.TXT found on the root directory. Any changes or errors found on this volume after its production can be found at the web site: www.igpp.ucla.edu/public/pds/ERRATA/VG_1501/ERRATA.TXT. 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 on this CD (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. Please note also that the /DATA directory is listed out of alphabetical order to make this tree more readable.
