This disk contains plasma data from the Deep Space 1 (DS1) Borrelly encounter 
submitted by the Plasma Experiment for Planetary Exploration (PEPE) team      
to the Planetary Data System (PDS). This data set contains ion and electron   
flux as a function of energy and angle, and ion composition data acquired     
during the DS1 encounter with comet 19P/Borrelly. The data are uncalibrated   
and provided in spacecraft coordinates. The data set covers the time period   
from 2001 days 262 - 266 (Sept. 19-23). The DS1 encounter occurred on         
September 22, 2001 (day of year 265), at a distance of 1.36 astronomical      
units from the Sun.

All data files are stored in the 'DATA' branch of the directory tree.         
Data are stored in both ASCII and binary tables. All files give time values   
in Spacecraft Event Time (SCET).                                              
                                                                              
All data files on this volume are described by detached PDS labels (.LBL).    
Documentation formatted for inclusion in the PDS catalog can be found in      
the CATALOG directory. Additional documentation is generally located in the   
DOCUMENT directory. Calibration information is found in the CALIB             
directory.

The disk is organized into a hierarchical directory structure.  The disk      
is formatted according to UDF/ISO bridge standards in order to accommodate    
users on a wide variety of platforms.

All data files are described by detached PDS labels.  A                       
detached label file has the same name as the data file that it                
describes, but with the extension LBL.  For example, the file                 
ELC01263.TAB is accompanied by the detached label file ELC01263.LBL in        
the same directory.                                                           
                                                                              
All document, detached PDS labels, and HTML files are stream                  
format files, with a carriage return (ASCII 13) and a line feed               
character (ASCII 10) at the end of the record.  This allows the files         
to be read by MacOS, DOS, Windows, Unix, and VMS operating systems.           
Unix system and Macintosh users will see the unnecessary carriage             
return character (^M) at the end of each line. Mac users will see an          
unnecessary line feed (^J) character at the start of each line.               
                                                                              
ASCII tabular data files (*.TAB) are formatted so that they may be            
read directly into many database management systems (DBMS) or                 
spreadsheet programs on various computers.  All fields are of fixed           
length and are separated by white space (blank characters or commas).         
Character fields are generally left justified, and numeric fields are         
decimal-aligned.  The 'start byte' and 'bytes' values listed in a PDS         
label do not include the white space between 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.                  
                                                                              
PDS labels are object-oriented.  The object to which the label                
refers (e.g., TIME_SERIES, TABLE, etc.) is denoted by a statement of          
the form:                                                                     
                                                                              
          ^object = location                                                  
                                                                              
in which the caret character (^, also called a pointer in this                
context) indicates that the object starts at the given location.  For         
an object in the same file as the label, the location is an integer           
representing the starting record number or byte of the object (the first      
record/byte in the file is 1).  For an object located outside the             
label file, the location denotes the name of the file containing the          
object, along with the starting record or byte number.  For example:          
                                                                              
^TIME_SERIES            = ("20903684.DAT", 3)                                 
                                                                              
indicates that the TIME_SERIES object begins at record 3 of the file          
20903684.DAT, in the same directory as the detached label file. Below         
is a list of the possible formats that use the ^object keyword.

where          n    is the starting record or byte number of the object,      
                    counting from beginning of the file (record 1,            
                    byte 1); default is record number.

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.

The person most directly responsible for the construction and release of this

this disk was created and understands as much about the disk structure and    
data organization as anyone. Other PPI personnel who may be aware of about    
issues related to this volume include Mr. Bill Harris, and Dr. Raymond Walker,
the PDS/PPI Node manager.
