Introduction
This CDROM is a remake of the PDS volume ULY_5001 that has been produced for the ESA Special Publication 1230. There are 8 volumes of Ulysses prime mission data in SP-1230, of which only this volume is a PDS product. The differences between this volume and the previous release are fairly minor:

- HTML interface to the CDROM added

- COSPIN-LET timetag errors corrected in corrupted data files (see ERRATA.TXT)

- New EPAC Pulse Height data set added (ULY-J-EPAC-4-SUMM-PHA-24HR-V1.0)

- New GAS sky map data set added (ULY-J-GAS-5-SKY-MAPS-V1.0)

- New COSPIN-KET document added

- DUST data set removed from this disk (see note in ERRATA.TXT)

- URAP b/w postscript spectragrams replaced with color plots

- New DDS data (additional time coverage and format change) included

This disk contains data submitted to the Planetary Data System (PDS) by the Ulysses COSPIN, EPAC, GAS, GRB, HISCALE, SCE, SWOOPS, URAP, and VHM/FGM investigators, and SPICE ephemeris data provided by NAIF, for the Ulysses Jupiter Encounter, 1992-01-25 to 1992-02-17 (days 25-48 inclusive). Note, that this archive does not include SWICS or SWOOPS ion data. The PDS acquired most of these data indirectly from the Ulysses Data System (UDS).

Data in this archive differ slightly from the original UDS archive data products. The original data submissions to the UDS all had different time tag styles and missing data values. At the recommendation of the UDS' governing body, these have been modified to provide uniform time styles and missing data values for all data sets.

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 is organized into 7 principal sub-directories:

CATALOG PDS catalog templates describing the Ulysses mission, spacecraft, instruments, data sets, key personnel and references
DATA science data from the following instruments: COSPIN (Cosmic Ray and Solar Particle Investigation), DDS (Ulysses Dust Detection System), EPAC (Energetic Particle Composition Experiment), GRB (Solar X-Ray/Gamma-Ray Burst Instrument), HISCALE (Heliospheric Instrument for Spectra, Composition, and Anisotropy at Low Energies), SCE (Solar Corona Experiment), SWOOPS (Solar Wind Observations Over the Poles of the Sun), URAP (Unified Radio and Plasma Experiment), and VHM/FGM (Magnetic Field Experiment).
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 in ASCII (.TAB) 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 CD-ROM (in the /DOCUMENT sub-directories) include copyrighted materials previously published in Astronomy and Astrophysics Supplement Series, Ulysses Instruments Special Issue, Vol. 92, No. 2, pp 207-440, January 1992. These materials appear with the permission of Astronomy and Astrophysics (A&A). A&A retains Copyright over these articles. Please see the Copyright statement appearing at the beginning of each of the A&A 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-ROM are completely PDS Standards Version 3.2 compliant.

Data files are stored in ASCII (.TAB) 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 CD-ROM 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-ROM, please refer to the file ERRATA.TXT found on the root directory. Changes or errors found after production can be found via anonymous-ftp at ftp.igpp.ucla.edu. Login as 'anonymous' and provide your e-mail address as a password (in order to provide an audit trail). Change directories to ERRATA/ULY_5001 (cd ERRATA/ULY_5001), and transfer the file ERRATA.TXT (get 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-ROM (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.
