END_OBJECT = TEXT END Voyagers 1 and 2 at Jupiter, Saturn, Uranus, and Neptune PRA High Resolution Lowband Data DVD-R (VGPR_1201) of the Planetary Data System ============================================================================== Introduction ============================================================================== This DVD-R contains the 6 second high resolution and lowband Radio Astronomy data recorded during the Voyagers 1 and 2 Jupiter and Saturn encounters, and the 60 millisecond high rate Radio Astronomy data during the Voyager 2 Uranus and Neptune encounters. Those data were submitted to the Planetary Data System (PDS) by Voyager PRA investigators. This volume covers the following encounter intervals: Voyager 1 Jupiter: 1979-01-06 to 1979-04-13 Voyager 1 Saturn: 1980-08-22 to 1980-12-14 Voyager 2 Jupiter: 1979-04-25 to 1979-08-04 Voyager 2 Jupiter: 1981-06-05 to 1981-09-28 Voyager 2 Uranus: 1985-10-24 to 1988-07-14 Voyager 2 Neptune: 1989-05-25 to 1989-09-27. Voyager 2 Uranus and Neptune encounter data have been previously published as VG_1002 (Uranus) and VG_1001 (Neptune). We include those data on this volume for user convenience. 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 DVD-R is organized into 10 principal sub-directories: CATALOG PDS catalog files describing the Voyager mission, and spacecraft, and PRA instruments, data sets, key personnel and references.

VG2_NEPTUNE Radio Astronomy data from Voyager 2 during Neptune encounter. 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 ============================================================================== Data from Jupiter and Saturn encounters are stored in ASCII format in their associated data directories. While data from Uranus and Neptune encounters are stored as BINARY files. Each data file is described by a detached PDS label file (.LBL). A file named INFO.TXT provides additional information about data sets 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 DVD-R (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 DVD-R 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. ============================================================================ Documents ============================================================================ The documents provided on this DVD-R (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.

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 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 on this DVD-R are completely PDS Standards Version 3.4 compliant. Data files are stored in ASCII (.TAB) and binary (.DAT) format. The file records are generally fixed length with space or comma delimited fields or columns. Refer to the label (.LBL) for information about the format and structure of a specific data file. Document files are reproduced from articles on the Space Science Reviews, and are stored 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. PDS labels are object-oriented. The object to which the label refers (e.g., SERIES, TABLE, etc.) is denoted by a statement of the form: ^object = location in which the caret character (^, also called a pointer in this context) indicates that the object starts at the given location. For an object in the same file as the label, the location is an integer representing the starting record number or byte of the object (the first record/byte in the file is 1). If this value is omitted, then the data begin at record one (1). For an object located outside the label file, the location denotes the name of the file containing the object, along with the starting record or byte number. Examples: ^TABLE = "ELE_MOM.TAB" The first example points would tell the user that file ELE_MOM.TAB is described by a TABLE object and the data begin at record 1 of the file. The data file exists in the same directory as the detached label file. Below is a list of the possible formats that use the ^object keyword. ^object = n ^object = n ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) where n is the starting record or byte number of the object, counting from beginning of the file (record 1, byte 1); default is record number. indicates that number given is in units of bytes. filename is upper-case file name. ext is upper-case file extension. [dirlist] is a period-delimited path-list of parent directories, in upper case, that specifies the object file directory (used only when the object is not in the same directory as the label file).* * All PDS labels on this volume are located in the same directory as the file they describe, so this construct is not used here. ============================================================================ Errata ============================================================================ There is a file called ERRATA.TXT found at the root level of this volume which contains a list of known deficiencies or caveats associated with data on this volume at the time this DVD-R was published.
