Introduction
==============================================================================
This disk contains Venus Orbital Operations data submitted to the Planetary Data
System (PDS) by PVO ONMS project investigators. 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 contains data for orbits 1-5055 covering the time period between
1978-12-05 through 1992-10-07. All data files are stored in the "DATA" branch
of the directory tree. Data are stored in ASCII table format (*.TAB). Each file
has a corresponding PDS label file, *.LBL.
Users of this disk should read the INFO.TXT file located in the DATA directory
which explains where each type of data is located, as well as the INFO.TXT files
located in each data directory which describe the data in that directory.
Novice users can ignore all directories and files except for those mentioned
in this brief description.

==============================================================================
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 PVO ONMS CD-ROM
(volume set PV03) created by this production date.
Any changes or errors that were found to any PV03 CD-ROM after the production
of this volume can be found via anonymous-ftp at pdsppi.igpp.ucla.edu
(ftp 128.97.68.54). The account name is anonymous and the password should be
your e-mail address (it's nice to leave an audit trail). Change to the PDS
errata directory (cd ERRATA/PV03), and transfer the file ERRATA.TXT
(get ERRATA.TXT).
==============================================================================
Software
==============================================================================
The Planetary Plasma Interactions (PPI) Node of NASA's Planetary Data System
(PDS) provides software to facilitate the location of the data of interest on
CD-ROM data products, as well as software to convert data between architecture
specific data formats. In addition, the PPI Node provides software which has
been made available by individual projects which may be useful when working
with PPI data. Non-PDS software is provided "as is" and is distributed by the
PPI Node as a service to the community.
To obtain the most recent release of any PPI distributed software use anonymous
FTP to connect the PPI FTP server located at "pdsppi.igpp.ucla.edu". (Complete
instructions on using FTP can be found in the SOFTWARE directory in the file
"FTP.TXT").
==============================================================================
File Formats
==============================================================================
All files on this disk are described by detached version 3.0 PDS labels.
Version 3.0 of the PDS label does not support detached TEXT file labels,
however, TEXT file labels are detached on this disk. This is the only known
exception to the PDS version 3.0 standard.
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. There will also be a format
file which describes the physical structure of the data. This format file is
then pointed to by the label. Both the label file and the format
file (*.FMT) are all located in the same directory 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. Below is
a tree diagram of the CD-ROM, followed by a description of the directory
function and key files in each directory.
Note: There is a file called YMTRANS.TBL in every directory. This is
characteristic of the CD-ROM production software.
Also within each of the DATA sub-directories there is a file
called ZZINPUT.PDS which is a necessary production file, but
not for the user. Excuse any inconvenience that these files may cause.
The basic organization of the disk is as follows:
CD-ROM

+-CATALOG
|
+-DOCUMENT

+-INDEX

+-MANAGE

+-SOFTWARE

+-DATA------+
