1.  INTRODUCTION

This volume contains selected data sets from the 1989 Soviet 
Phobos mission to Mars, together with ancillary information 
produced by NASA Planetary Data System personnel. This disk 
is made for test purposes only, as a demonstration of PDS 
and NAIF (Navigation Ancillary Information Facility) 
techniques and standards for production of archive-quality 
data sets.


The data included on this disk are: 1) images from the VSK 
experiment (Mars and Phobos); 2) images from the Termoskan 
experiment (Mars); 3) spectrophotometric data from the KRFM 
experiment (Mars); 4) selected kernels produced using the 
SPICE system (geometry data). A set of PDS Catalog 
'templates' have been included, which capture documentation 
about the Phobos spacecraft, the Phobos mission, the 
instruments responsible for the data sets included here, and 
the data sets themselves. The PDS Data Dictionary document 
is included to aid data management personnel who desire to 
use this data base.  The image processing software IMDISP, 
which runs on IBM-compatible computers, is included. 
Additionally, the complete SPICE Toolkit of FORTRAN software 
is included. These assorted data sets and other information 
are arranged in directories, as follows: 
	VSK 
	TERMOSKAN 
	KRFM 
	LABEL 
	SOFTWARE 
	DOCUMENTATION

2.  DISC FORMAT

This disc has been formatted for use on IBM-PC and 
compatible computers.


3.  FILE NAMING CONVENTIONS

According to PDS file naming conventions, files that have 
the .tab conventions are files in a tabular format that have 
detailed descriptions elsewhere in the same subdirectory.  
The files that provide these descriptions have the extention 
.lbl.  Thus, in the INDEX subdirectories, readers will note 
pairs of files with the same file name, but with extensions 
of .tab and .lbl.  

Files with the extension .dat also exist.  On this disc 
these are ancillary data files that assist investigators in 
the understanding of data sets.

Files with the extension .txt are ASCII text files that 
provide explanations of data on the disc.


4.  LOCATIONS OF GENERAL INFORMATION

General information about the data on this disc may be found 
in the LABEL subdirectory.  The catalog.lbl file includes 
PDS templates that describe the Phobos mission and the 
Phobos 2 spacecrafts and its instruments.  The dataset.lbl 
file contains information on each data set on the disc.


5.  KEYWORD DEFINITIONS

Definitions for all keywords used in PDS labels may be found 
in the Planetary Science Data Dictionary (PSDD).  The 
dictionary has been provided on this disc in the DOCUMENT 
subdirectory.  It is formatted as a set of delimited-ASCII 
tables, in order to allow the users easy loading into a 
relational database system.  The original PSDD was 
maintained on a personal computer using the Paradox 3.5 
relational database software package.  In the form provided, 
it may be loaded onto any relational database system.

The Planetary Science Data Dictionary is also available in
book form.  For information about the book, or about this
electronic copy, the reader may contact:
