Introduction
==============================================================================

This disk contains Venus Orbital Operations data submitted to the Planetary
Data System (PDS) by PVO project Magnetometer and Electric Field Detector
principal 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 1-40 covering the time period between
1978-12-05 through 1979-01-14. All data files are stored in the "DATA" branch
of the directory tree. Data are stored in IGPP flatfile form that is a binary
representation of data ( *.FFD) plus a detached header file (*.FFH) which
describes the structure of the data file to software. Software to read IGPP
flatfiles and convert data to ASCII can be found on disk 1 of this volume
series.

The Magnetometer data on this volume were acquired after the multiplexor
anomaly which resulted in only a single sensor (P sensor) returning data
to Earth. Data from this single sensor and the Inertial Spacecraft Coordinate
system, Z direction are provided on this volume. Without data from all
3 components, the data can not be rotated into geophysical coordinates

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 describes the data in that
directory. Although the INFO.TXT file is quite large, it contains the most
relevant information first. It begins by describing the type of data in the
directory, the orbits covered, and the names of the most useful user files.
Next the file naming conventions are described and the structure of the data
files are given. More detailed information about each data file is then given.

Novice users can ignore all directories and files except for those mentioned
in this brief description.

This volume contains a document version of the Mission template. This document
is supplemented by numerous scanned figures from the NASA Special publication
SP-518, 'Pioneering Venus: A Planet Unveiled' by Fimmel et al. Figures are
provided in either GIF format. This new version of the mission and host
template is provided to add completeness to the archive of these large
datasets. They contain information about the mission and the spacecraft that
would be difficult to capture with text alone. However, the information is
still incomplete. Users interested in the mission history or the details of
the spacecraft configuration or operation should obtain a copy of NASA SP-518.

==============================================================================
Volume Set Information
==============================================================================

This CD-ROM is the first disk of the PV01_xxxx series. This volume set
contains the processed data from the Magnetometer and Electric Field Detector
Team. Every volume will contain full resolution and 24 second averaged
magnetometer data in spacecraft coordinates, full resolution and 24 second
averaged electric field data, ephemeris data, engineering data, instrument
status data, and phase and offset data. The OMAG and OEFD have been averaged
over two spin periods (approximately 24 seconds). The averaging interval is
overlapped and data are output on single spin period centers, the time stamp
corresponding to the center of the averaging window. This volume set will
contain orbits 1-5055 (1978-12-05 to 1992-10-07.)

As the first disk of the series, this CD contains all catalog templates,
documentation, and software pertinent to the entire volume series.

==============================================================================
Errata
==============================================================================

There is a file called ERRATA.TXT found at the root level of this volume which
contains a list of changes and errors at the time this CD was published. This
is a list of cumulative changes made to any PVO OMAG/OEFD CD-ROM
(volume set PV01) created by this production date.

Any changes or errors that were found to any PV01 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 pds/ERRATA/PV01), and transfer the file ERRATA.TXT
(get ERRATA.TXT).

Changes can also be found through our web site at
http://www.igpp.ucla.edu/ssc/pdsppi/Welcome.html through the data access
system.

==============================================================================
File Formats
==============================================================================

Detached version 3.x PDS labels describe all files on this disk.
Most of the data files are time-series that are organized as IGPP flatfiles.
An IGPP flatfile is a collection of 2 files, each of which could be considered
a table. The data file (.FFD) is a binary table of data values. The header
file (.FFH) is an ASCII table which describes the data file (.FFD) and is
used by the UCLA/IGPP Data Flow System (a software package).

PDS labels are identified by a ".LBL" file name extension. There is one label
file for each text and data file (1 flatfile) contained on this disk and the
file name prefix is the same as the file the label describes. If the dataset
is stored as multiple files (as most of them are), there will be a single
format file which describes the physical structure of the data. This format
file is then pointed to by all of the labels. Both the label files and the
format files (*.FMT) are all located in the same directories 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 (VAX / IBM-PC) format.

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 (IBM/Windows and IBM/WindowsNT platforms),
as well as, software to rotate the magnetometer data from
spacecraft to Venus Solar Orbital (VSO) coordinates (PVROT),
and convert the binary data files to ASCII (FFEXTRACT)
(IBM/Windows, IBM/WindowsNT, UNIX/SunOS, and UNIX/Solaris platforms).

Software to merge files (FFMERGE) is also available from the PDS/PPI Node.

The SOFTWARE directory contains the installation procedures for all software
on this disk.

Executables for the above mentioned systems are provided on this disk, as
well as the source code. The source codes have been zip'ed for easier
packaging. In the case that one's local unzip software is unsuccessful,
InfoZip's Unzip source code has also been provided. 

To obtain the most recent release of any PPI distributed software (source
code and executables) 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").

Cognizant Persons
==============================================================================

The person most directly responsible for the construction and release of this
CD-ROM is Mr. Steven Joy. He was the PPI Node Data Administrator at the time
this disk was created and he understands as much about the disk structure and
data organization as anyone. The construction of the PDS labels and templates
was done by Ms. Eva Fried and Ms. Muriel Kniffin of the PPI Node and
Ms. Sue Hess and Ms. Ruth Monarrez of the Central Node at JPL. Mr. Mike Martin
and Mr. Tyler Brown of JPL has helped to insure this disk conforms to PDS
standards.
