Introduction
============
This dataset was originally part of a larger IHW multi-dataset volume,
HAL_0025.
This dataset contains GIOTTO magnetometer 8-second observations of 1P/Halley.
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 volume 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.
Re-organized International Halley Watch (IHW) Data Sets
=======================================================
The original IHW volumes HAL_0025 and HAL_0026 contain data from
several spacecraft that flew by comets Halley and Giacobini-Zinner,
over 40 data sets in all on the 2 volumes. The data were sorted
into subdirectories by spacecraft and instrument, with shared
supporting directories.
The data were also archived under a fairly early form of the PDS
Standards, and formatted to an equally early form of the FITS table
standard, where appropriate, occasionally producing some arcane
formats for the modern user - including PDS labels with deprecated
terminology and FITS files that sometimmes have their header segments
separated from their data segments.
The reorganization effort sought to separate the data files constituting
the unique data sets into a more contemporary, single-data-set-per-volume
format for ease of access and distribution. The data have been sorted
into a subdirectory hierarchy based on observation date, unless the number
of data files was small enough that this seemed more disruptive than
helpful, in which case all the observations are located directly in the
DATA/ subdirectory.
Although the original disks included executable files for some simple
utilities, these have been omitted from the reorganized data. No modern
system would run the executables, and in most cases no source code was
provided. For those rare cases where source was provided, it has been
relocated to a relevant support directory where its principal value is
as documentation. Note that PDS does not and will not support this code.

Brief Volume Description
========================
This data set is organized into 5 principal sub-directories:
CATALOG PDS catalog templates describing the mission, spacecraft,
instrument, and data set
DATA science data
DOCUMENT documents describing the mission, instrument and/or dataset
INDEX index of all user files contained on this volume
GEOMETRY contains ephemeris information and related files
Contacts

The person most directly responsible for the construction and release of
this volume is Mr. Steven Joy. He was the PPI Node Data Administrator at the
time this volume was created and understands as much about the structure
and data organization as anyone. Other PPI personnel who may be aware of
about issues related to this volume include Dr. Raymond Walker, the PDS/PPI
node manager.

This compact disk (CD-ROM) is one of a 2-disk set containing data
obtained through the efforts of the International Halley Watch (IHW)
Disciplines and the Lead Center. These volumes are devoted to data
returned by the intercept spacecraft for comet Halley and the International
Cometary Explorer (ICE) for comet Giacobini-Zinner as listed below:

These are the last CD-ROMs of the Comet Halley archive, volumes 25 and 26.
In addition to the data themselves, the disks contain a wide variety of
supporting files and tools for the Archive user; the major categories are
documentation, ephemeris information, searchable tables and indices, and
software (source code as well as executable modules). These have been
organized into three principal directories one level below the root: DOCUMENT
INDEX, and SOFTWARE. It is suggested that the Archive user review the
document files listed below before roaming through the multi-level data
directories. There is one file, CDSTRUCT, in the DOCUMENT directory that
is a complete listing of files (with path) organized by Logical Block Number.
/DOCUMENT/VOLINFO.TXT Brief guide to use of disks
/DOCUMENT/CDTREE.TXT Schematic, annotated layout of disk
/DOCUMENT/ESA_1066/*.TXT A brief description of each mission
/DOCUMENT/ESA_1077/*.TXT A brief description of GIOTTO experiments
The time period covered for this volume (25) is March 03-14, 1986.
All of the text files on this disk have fixed length records padded to
80 or 132 bytes per record. The last two characters of each record are
a carriage return and line feed. This has been done to files with the
following extensions (*.DOC, *.LBL, and *.TXT).
