Stardust-NExT archive data set for NAVCAM RDR data.                           
                                                                              
This file is the "Read me first" file for this data set.  Its purpose is to   
be the starting point for any user who wishes to view and understand the data 
in this data set.  It contains a high-level description of the contents of    
this data set, and points the user to other documents in this data set that   
contain more detailed descriptions of the data along with pointers to         
additional documentation.  If the information in this data set is represented 
as a tree, with each file as a leaf covering a specific area or sampled data, 
then this file is the root of the tree.  Some of the 'leaves' contain         
reference to external information sources such as journal articles or other   
data sets; those references are considered an integral part of this data set  
and are often critical for understanding the data.                            
                                                                              
All of the data sets for the Stardust-NExT mission instrument data have been  
prepared in a similar manner, so the "Read me first" files for these data     
sets will be similar.

This volume contains NAVCAM CODMAC level 3 products from the Stardust-NExT    
mission.  It also contains documentation which describes these products.      
                                                                              
                                                                              
1.1) Quick start:                                                             
-----------------                                                             
                                                                              
The data set files are laid out with a directory (a.k.a. folder) structure.   
The most important top-level directories are CATALOG/, DOCUMENT/ and DATA/.   
                                                                              
The CATALOG/ directory contains high-level PDS catalog files which describe   
the mission, spacecraft, instrument and other information related to this     
data set.  The catalog files also contain references to external materials    
such as journal articles.  See CATALOG/CATINFO.TXT for more details.          
                                                                              
The DOCUMENT/ directory contains more detailed descriptions of this data set. 
 See DOCUMENT/DOCINFO.TXT for more details.                                   
                                                                              
The DATA/ directory contains the data in this data set.  Subdirectories       
partition the data by date and/or by target.  Each data product has a         
corresponding PDS data label in accordance with the Planetary Data System     
(PDS) Standards reference, Version 3.8, document JPL D-7669.  See             
DOCUMENT/DATAINFO.TXT for more details.                                       
                                                                              
The BROWSE/ directory contains a browsing facility for the data.  See         
BROWSE/BROWINFO.TXT for more details.                                         
                                                                              
                                                                              
1.2) Product description                                                      
------------------------                                                      
                                                                              
Each NAVCAM calibrated (RDR) product comprises several sections:  the image   
pixel data from the CCD calibrated to spectral radiance; the BaseLine         
Stabilization (BLS or bias) pixels from the CCD electronics; the prefix table 
from the instrument telemetry; the image histogram from the ground data       
system; the original PDS label from the ground data system; a quality map of  
the image; an uncertainty map; a signal-to-noise ratio (SNR) map.             
                                                                              
See also DATA/DATAINFO.TXT, CATALOG/DATASET.CAT and DOCUMENT/DOCINFO.TXT for  
further details.                                                              
                                                                              
The products archived in this volume have all been released by the            
Stardust-NExT Project.                                                        
                                                                              
                                                                              
2) Data set medium format                                                     
=========================                                                     
                                                                              
This data set has been delivered to PDS in an electronic format, transferred  
via either the Internet or portable disk drive.  User access will typically   
be via a web browser over the Internet to a web server at the Small Bodies    
Node of PDS (currently http://pdssbn.astro.umd.edu/).  Duplicating the        
directory hierarchy and contents recursively from the directory which         
contains this AAREADME.TXT file and below is all that is required to copy     
this data set.                                                                
                                                                              
                                                                              
3) File format                                                                
==============                                                                
                                                                              
Each data product and all files with content have a PDS label.  The PDS label 
is the definitive and complete source describing the data layout and format   
in each product in this data set.  The PDS label may be attached or detached. 
 Attached labels are in the same file as the data at the start of the file.   
Detached labels are separate files with pointers to the data files; detached  
label filenames always end in .LBL or .lbl.  The label files conform to the   
Planetary Data System (PDS) Standards, Version 3.8, Jet Propulsion Laboratory 
(JPL) document JPL D-7669 Part 2; refer to this standards reference for       
details in interpreting the label and contents of any file in this data set.  
                                                                              
PDS labels for data products also contain parameter values such as the start  
and end times of the data in the data product.                                
                                                                              
NAVCAM image data products are stored as Primary Data Unit (PDU) images and   
multiple Extension Data Units (EDUs) in FITS files; see                       
                                                                              
  http://fits.gsfc.nasa.gov/iaufwg/iaufwg.html                                
                                                                              
FITS-savvy users may use existing FITS software to view and process these     
data.  However, the PDS labels adequately describe both the conditions of     
each observation (geometry, camera parameters, &c) and the data layout and    
format in the files, so FITS software is not necessary to work with these     
data.  The FITS headers in the files were developed for use by the science    
team and are provided as-is with no documentation beyond the comments that    
follow most FITS header keyword values.                                       
                                                                              
All detached label files contain 80-byte fixed-length records, with a         
carriage return character (ASCII 13) in the 79th byte and a line feed         
character (ASCII 10) in the 80th byte.  This format allows the files to be    
read by many different operating systems (e.g. MacOS, Windows, DOS, Unix,     
Linux, VMS etc.).   All tabular files are also described by PDS labels,       
either embedded at the beginning of the file (attached) or detached.  If      
detached, the PDS label file has the same, or a similar, name as the data     
file(s) it describes, with the extension .LBL; for example, the file          
INDEX.TAB is accompanied by the detached label file INDEX.LBL in the same     
directory.                                                                    
                                                                              
Tabular files are formatted so that they may be read directly into many       
database management systems on various computers. All fields are separated by 
commas, and character fields are enclosed in double quotation marks (").      
Character fields are left justified, and numeric fields are right justified.  
The "start byte" and "bytes" values listed in the labels do not include the   
commas between fields or the quotation marks surrounding character fields.    
The records are of fixed length, and the last two bytes of each record        
contain the ASCII carriage return and line feed characters. This allows a     
table to be treated as a fixed length record file on computers that support   
this file type and as a normal text file on other computers.                  
                                                                              
                                                                              
4) Data set contents and directory layout

================================                                              
                                                                              
As noted above, this data set was delivered to PDS-SBN in electronic format.  
Any computer system capable of replicating the directory (folder) structure   
should be able to maintain a usable copy of this data set.  At the time of    
the delivery of this data set (2011 A.D.), that specification will be met by  
computers running the following operating systems:  Microsoft Windows; Apple  
Mac OSX; Unix(tm) derivatives including Linux; VMS.                           
                                                                              
Tabular data may be imported into a spreadsheet application (OpenOffice.org   
Spreadsheet or Microsoft Office Excel) or a database application (MySQL,      
PostgreSQL, Microsoft SQL Server or Microsoft Office Access).  Tabular data   
may also be viewed with a PDS tool called NasaView:

PDS supplies tools that may be of use in viewing the data files in this data  
set:

NAVCAM image data can be viewed with NasaView, as well as by using FITS       
libraries within other programming environments:                              
                                                                              
  FITSIO library in several environments (C, FORTRAN, etc.)                   
    (http://heasarc.gsfc.nasa.gov/fitsio/)                                    
  Native FITS reader in Matlab                                                
  IDL Astronomy Library (http://idlastro.gsfc.nasa.gov/)                      
                                                                              
Documentation and data labels may be viewed with word processing              
applications:  OpenOffice.org Word Processor; Microsoft Office Word; editors  
such as VI, VIM, GEDIT and others in the Linux/Unix(tm) environment.  ASCII   
files, such as tables and PDS labels, may be viewed with many web browsers.   
                                                                              
Some documentation files are stored as PDF (Portable Document Format) files;  
PDF filenames will end in .PDF (case-insensitive).  A PDF reader (e.g.        
Acrobat reader on Windows and Mac OSX, acroread on Unix, Document Viewer on   
Linux, or a PDF plug-in for a web browser) is necessary to view these files,  
but in the absence of such readers all PDF documents also have alternate      
versions that will be easier to view.                                         
                                                                              
                                                                              
6) Errata, Disclaimer and PDSDD

A cumulative list of anomalies and errors is maintained in the file           
ERRATA.TXT at the root directory of this volume.  Over time and multiple      
versions of this data set it is anticipated that the errors will be corrected 
and the anomalies incorporated into the data set documentation.  Users should 
always check the latest ERRATA.TXT file for this data set before using the    
data for any purpose.                                                         
                                                                              
Although considerable care has gone into making this volume, errors are both  
possible and likely.  Users of the data are advised to exercise the same      
caution as they would when dealing with any other unknown data set.           
                                                                              
At the time of delivery of this data set no known anomalies exist and the     
ERRATA.TXT file comprises only its attached label.                            
                                                                              
Reports of errors or difficulties would be appreciated. Please contact one of 
the persons listed herein.

This data set presupposes and proposes the following STANDARD_VALUE_SET       
entries will be added to the PDS Data Dictionary; see also the file           
PDSDD_NEXT.FULL in the EXTRAS/ directory.  Until those entries are added, PDS 
validation tools may generate errors and/or warnings when run against this    
data set.  Changes proposed for all Stardust-NExT instrument data sets (CIDA, 
DFMI, NAVCAM) are included here so PDS personnel do not have to browse        
several data sets to compile the proposed changes.
